+/**
+ * @fileoverview
+ * some functions for browser-side pretty printing of code contained in html.
+ *
+ * <p>
+ * For a fairly comprehensive set of languages see the
+ * <a href="http://google-code-prettify.googlecode.com/svn/trunk/README.html#langs">README</a>
+ * file that came with this source.  At a minimum, the lexer should work on a
+ * number of languages including C and friends, Java, Python, Bash, SQL, HTML,
+ * XML, CSS, Javascript, and Makefiles.  It works passably on Ruby, PHP and Awk
+ * and a subset of Perl, but, because of commenting conventions, doesn't work on
+ * Smalltalk, Lisp-like, or CAML-like languages without an explicit lang class.
+ * <p>
+ * Usage: <ol>
+ * <li> include this source file in an html page via
+ *   {@code <script type="text/javascript" src="/path/to/prettify.js"></script>}
+ * <li> define style rules.  See the example page for examples.
+ * <li> mark the {@code <pre>} and {@code <code>} tags in your source with
+ *    {@code class=prettyprint.}
+ *    You can also use the (html deprecated) {@code <xmp>} tag, but the pretty
+ *    printer needs to do more substantial DOM manipulations to support that, so
+ *    some css styles may not be preserved.
+ * </ol>
+ * That's it.  I wanted to keep the API as simple as possible, so there's no
+ * need to specify which language the code is in, but if you wish, you can add
+ * another class to the {@code <pre>} or {@code <code>} element to specify the
+ * language, as in {@code <pre class="prettyprint lang-java">}.  Any class that
+ * starts with "lang-" followed by a file extension, specifies the file type.
+ * See the "lang-*.js" files in this directory for code that implements
+ * per-language file handlers.
+ * <p>
+ * Change log:<br>
+ * cbeust, 2006/08/22
+ * <blockquote>
+ *   Java annotations (start with "@") are now captured as literals ("lit")
+ * </blockquote>

+ * Fake HTTP backend implementation suitable for unit testing applications that use the
+ * {@link ng.$http $http service}.
+ *
+ * *Note*: For fake HTTP backend implementation suitable for end-to-end testing or backend-less
+ * development please see {@link ngMockE2E.$httpBackend e2e $httpBackend mock}.
+ *
+ * During unit testing, we want our unit tests to run quickly and have no external dependencies so
+ * we don’t want to send {@link https://developer.mozilla.org/en/xmlhttprequest XHR} or
+ * {@link http://en.wikipedia.org/wiki/JSONP JSONP} requests to a real server. All we really need is
+ * to verify whether a certain request has been sent or not, or alternatively just let the
+ * application make requests, respond with pre-trained responses and assert that the end result is
+ * what we expect it to be.
+ *
+ * This mock implementation can be used to respond with static or dynamic responses via the
+ * `expect` and `when` apis and their shortcuts (`expectGET`, `whenPOST`, etc).
+ *
+ * When an Angular application needs some data from a server, it calls the $http service, which
+ * sends the request to a real server using $httpBackend service. With dependency injection, it is
+ * easy to inject $httpBackend mock (which has the same API as $httpBackend) and use it to verify
+ * the requests and respond with some testing data without sending a request to real server.
+ *
+ * There are two ways to specify what test data should be returned as http responses by the mock
+ * backend when the code under test makes http requests:
+ *
+ * - `$httpBackend.expect` - specifies a request expectation
+ * - `$httpBackend.when` - specifies a backend definition
+ *
+ *
+ * # Request Expectations vs Backend Definitions
+ *
+ * Request expectations provide a way to make assertions about requests made by the application and
+ * to define responses for those requests. The test will fail if the expected requests are not made
+ * or they are made in the wrong order.
+ *
+ * Backend definitions allow you to define a fake backend for your application which doesn't assert
+ * if a particular request was made or not, it just returns a trained response if a request is made.
+ * The test will pass whether or not the request gets made during testing.
+ *
+ *
+ * <table class="table">
+ *   <tr><th width="220px"></th><th>Request expectations</th><th>Backend definitions</th></tr>
+ *   <tr>
+ *     <th>Syntax</th>
+ *     <td>.expect(...).respond(...)</td>
+ *     <td>.when(...).respond(...)</td>
+ *   </tr>
+ *   <tr>
+ *     <th>Typical usage</th>
+ *     <td>strict unit tests</td>
+ *     <td>loose (black-box) unit testing</td>
+ *   </tr>
+ *   <tr>
+ *     <th>Fulfills multiple requests</th>
+ *     <td>NO</td>
+ *     <td>YES</td>
+ *   </tr>
+ *   <tr>
+ *     <th>Order of requests matters</th>
+ *     <td>YES</td>
+ *     <td>NO</td>
+ *   </tr>
+ *   <tr>
+ *     <th>Request required</th>
+ *     <td>YES</td>
+ *     <td>NO</td>
+ *   </tr>
+ *   <tr>
+ *     <th>Response required</th>
+ *     <td>optional (see below)</td>
+ *     <td>YES</td>
+ *   </tr>
+ * </table>
+ *
+ * In cases where both backend definitions and request expectations are specified during unit
+ * testing, the request expectations are evaluated first.
+ *
+ * If a request expectation has no response specified, the algorithm will search your backend
+ * definitions for an appropriate response.
+ *
+ * If a request didn't match any expectation or if the expectation doesn't have the response
+ * defined, the backend definitions are evaluated in sequential order to see if any of them match
+ * the request. The response from the first matched definition is returned.
+ *
+ *
+ * # Flushing HTTP requests
+ *
+ * The $httpBackend used in production always responds to requests with responses asynchronously.
+ * If we preserved this behavior in unit testing we'd have to create async unit tests, which are
+ * hard to write, understand, and maintain. However, the testing mock can't respond
+ * synchronously because that would change the execution of the code under test. For this reason the
+ * mock $httpBackend has a `flush()` method, which allows the test to explicitly flush pending
+ * requests and thus preserve the async api of the backend while allowing the test to execute
+ * synchronously.
+ *
+ *
+ * # Unit testing with mock $httpBackend
+ * The following code shows how to setup and use the mock backend when unit testing a controller.
+ * First we create the controller under test:
+ *
+  <pre>
+  // The controller code
+  function MyController($scope, $http) {
+    var authToken;
+
+    $http.get('/auth.py').success(function(data, status, headers) {
+      authToken = headers('A-Token');
+      $scope.user = data;
+    });
+
+    $scope.saveMessage = function(message) {
+      var headers = { 'Authorization': authToken };
+      $scope.status = 'Saving...';
+
+      $http.post('/add-msg.py', message, { headers: headers } ).success(function(response) {
+        $scope.status = '';
+      }).error(function() {
+        $scope.status = 'ERROR!';
+      });
+    };
+  }
+  </pre>
+ *
+ * Now we setup the mock backend and create the test specs:
+ *
+  <pre>
+    // testing controller
+    describe('MyController', function() {
+       var $httpBackend, $rootScope, createController;
+
+       beforeEach(inject(function($injector) {
+         // Set up the mock http service responses
+         $httpBackend = $injector.get('$httpBackend');
+         // backend definition common for all tests
+         $httpBackend.when('GET', '/auth.py').respond({userId: 'userX'}, {'A-Token': 'xxx'});
+
+         // Get hold of a scope (i.e. the root scope)
+         $rootScope = $injector.get('$rootScope');
+         // The $controller service is used to create instances of controllers
+         var $controller = $injector.get('$controller');
+
+         createController = function() {
+           return $controller('MyController', {'$scope' : $rootScope });
+         };

+ * @description
+ * Fake HTTP backend implementation suitable for end-to-end testing or backend-less development of
+ * applications that use the {@link ng.$http $http service}.
+ *
+ * *Note*: For fake http backend implementation suitable for unit testing please see
+ * {@link ngMock.$httpBackend unit-testing $httpBackend mock}.
+ *
+ * This implementation can be used to respond with static or dynamic responses via the `when` api
+ * and its shortcuts (`whenGET`, `whenPOST`, etc) and optionally pass through requests to the
+ * real $httpBackend for specific requests (e.g. to interact with certain remote apis or to fetch
+ * templates from a webserver).
+ *
+ * As opposed to unit-testing, in an end-to-end testing scenario or in scenario when an application
+ * is being developed with the real backend api replaced with a mock, it is often desirable for
+ * certain category of requests to bypass the mock and issue a real http request (e.g. to fetch
+ * templates or static files from the webserver). To configure the backend with this behavior
+ * use the `passThrough` request handler of `when` instead of `respond`.
+ *
+ * Additionally, we don't want to manually have to flush mocked out requests like we do during unit
+ * testing. For this reason the e2e $httpBackend automatically flushes mocked out requests
+ * automatically, closely simulating the behavior of the XMLHttpRequest object.
+ *
+ * To setup the application to run with this http backend, you have to create a module that depends
+ * on the `ngMockE2E` and your application modules and defines the fake backend:
+ *
+ * <pre>
+ *   myAppDev = angular.module('myAppDev', ['myApp', 'ngMockE2E']);
+ *   myAppDev.run(function($httpBackend) {
+ *     phones = [{name: 'phone1'}, {name: 'phone2'}];
+ *
+ *     // returns the current list of phones
+ *     $httpBackend.whenGET('/phones').respond(phones);
+ *
+ *     // adds a new phone to the phones array
+ *     $httpBackend.whenPOST('/phones').respond(function(method, url, data) {
+ *       phones.push(angular.fromJson(data));
+ *     });
+ *     $httpBackend.whenGET(/^\/templates\//).passThrough();
+ *     //...
+ *   });
+ * </pre>
+ *
+ * Afterwards, bootstrap your app with this new module.

+   * @description
+   *
+   * *NOTE*: This function is also published on window for easy access.<br>
+   *
+   * The inject function wraps a function into an injectable function. The inject() creates new
+   * instance of {@link AUTO.$injector $injector} per test, which is then used for
+   * resolving references.
+   *
+   *
+   * ## Resolving References (Underscore Wrapping)
+   * Often, we would like to inject a reference once, in a `beforeEach()` block and reuse this
+   * in multiple `it()` clauses. To be able to do this we must assign the reference to a variable
+   * that is declared in the scope of the `describe()` block. Since we would, most likely, want
+   * the variable to have the same name of the reference we have a problem, since the parameter
+   * to the `inject()` function would hide the outer variable.
+   *
+   * To help with this, the injected parameters can, optionally, be enclosed with underscores.
+   * These are ignored by the injector when the reference name is resolved.
+   *
+   * For example, the parameter `_myService_` would be resolved as the reference `myService`.
+   * Since it is available in the function body as _myService_, we can then assign it to a variable
+   * defined in an outer scope.
+   *
+   * ```
+   * // Defined out reference variable outside
+   * var myService;
+   *
+   * // Wrap the parameter in underscores
+   * beforeEach( inject( function(_myService_){
+   *   myService = _myService_;
+   * }));
+   *
+   * // Use myService in a series of tests.
+   * it('makes use of myService', function() {
+   *   myService.doStuff();
+   * });
+   *
+   * ```
+   *
+   * See also {@link angular.mock.module angular.mock.module}
+   *
+   * ## Example
+   * Example of what a typical jasmine tests looks like with the inject method.
+   * <pre>
+   *
+   *   angular.module('myApplicationModule', [])
+   *       .value('mode', 'app')
+   *       .value('version', 'v1.0.1');
+   *
+   *
+   *   describe('MyApp', function() {
+   *
+   *     // You need to load modules that you want to test,
+   *     // it loads only the "ng" module by default.
+   *     beforeEach(module('myApplicationModule'));
+   *
+   *
+   *     // inject() is used to inject arguments of all given functions
+   *     it('should provide a version', inject(function(mode, version) {
+   *       expect(version).toEqual('v1.0.1');
+   *       expect(mode).toEqual('app');
+   *     }));
+   *
+   *
+   *     // The inject and module method can also be used inside of the it or beforeEach
+   *     it('should override a version and test the new version is injected', function() {
+   *       // module() takes functions or strings (module aliases)
+   *       module(function($provide) {
+   *         $provide.value('version', 'overridden'); // override version here

+ * A factory which creates a resource object that lets you interact with
+ * [RESTful](http://en.wikipedia.org/wiki/Representational_State_Transfer) server-side data sources.
+ *
+ * The returned resource object has action methods which provide high-level behaviors without
+ * the need to interact with the low level {@link ng.$http $http} service.
+ *
+ * Requires the {@link ngResource `ngResource`} module to be installed.
+ *
+ * @param {string} url A parametrized URL template with parameters prefixed by `:` as in
+ *   `/user/:username`. If you are using a URL with a port number (e.g.
+ *   `http://example.com:8080/api`), it will be respected.
+ *
+ *   If you are using a url with a suffix, just add the suffix, like this:
+ *   `$resource('http://example.com/resource.json')` or `$resource('http://example.com/:id.json')`
+ *   or even `$resource('http://example.com/resource/:resource_id.:format')`
+ *   If the parameter before the suffix is empty, :resource_id in this case, then the `/.` will be
+ *   collapsed down to a single `.`.  If you need this sequence to appear and not collapse then you
+ *   can escape it with `/\.`.
+ *
+ * @param {Object=} paramDefaults Default values for `url` parameters. These can be overridden in
+ *   `actions` methods. If any of the parameter value is a function, it will be executed every time
+ *   when a param value needs to be obtained for a request (unless the param was overridden).
+ *
+ *   Each key value in the parameter object is first bound to url template if present and then any
+ *   excess keys are appended to the url search query after the `?`.
+ *
+ *   Given a template `/path/:verb` and parameter `{verb:'greet', salutation:'Hello'}` results in
+ *   URL `/path/greet?salutation=Hello`.
+ *
+ *   If the parameter value is prefixed with `@` then the value of that parameter is extracted from
+ *   the data object (useful for non-GET operations).
+ *
+ * @param {Object.<Object>=} actions Hash with declaration of custom action that should extend the
+ *   default set of resource actions. The declaration should be created in the format of {@link
+ *   ng.$http#usage_parameters $http.config}:
+ *
+ *       {action1: {method:?, params:?, isArray:?, headers:?, ...},
+ *        action2: {method:?, params:?, isArray:?, headers:?, ...},
+ *        ...}
+ *
+ *   Where:
+ *
+ *   - **`action`** – {string} – The name of action. This name becomes the name of the method on
+ *     your resource object.
+ *   - **`method`** – {string} – HTTP request method. Valid methods are: `GET`, `POST`, `PUT`,
+ *     `DELETE`, and `JSONP`.
+ *   - **`params`** – {Object=} – Optional set of pre-bound parameters for this action. If any of
+ *     the parameter value is a function, it will be executed every time when a param value needs to
+ *     be obtained for a request (unless the param was overridden).
+ *   - **`url`** – {string} – action specific `url` override. The url templating is supported just
+ *     like for the resource-level urls.
+ *   - **`isArray`** – {boolean=} – If true then the returned object for this action is an array,
+ *     see `returns` section.
+ *   - **`transformRequest`** –
+ *     `{function(data, headersGetter)|Array.<function(data, headersGetter)>}` –
+ *     transform function or an array of such functions. The transform function takes the http
+ *     request body and headers and returns its transformed (typically serialized) version.
+ *   - **`transformResponse`** –
+ *     `{function(data, headersGetter)|Array.<function(data, headersGetter)>}` –
+ *     transform function or an array of such functions. The transform function takes the http
+ *     response body and headers and returns its transformed (typically deserialized) version.
+ *   - **`cache`** – `{boolean|Cache}` – If true, a default $http cache will be used to cache the
+ *     GET request, otherwise if a cache instance built with
+ *     {@link ng.$cacheFactory $cacheFactory}, this cache will be used for
+ *     caching.
+ *   - **`timeout`** – `{number|Promise}` – timeout in milliseconds, or {@link ng.$q promise} that
+ *     should abort the request when resolved.
+ *   - **`withCredentials`** - `{boolean}` - whether to set the `withCredentials` flag on the
+ *     XHR object. See {@link https://developer.mozilla.org/en/http_access_control#section_5
+ *     requests with credentials} for more information.
+ *   - **`responseType`** - `{string}` - see {@link
+ *     https://developer.mozilla.org/en-US/docs/DOM/XMLHttpRequest#responseType requestType}.
+ *   - **`interceptor`** - `{Object=}` - The interceptor object has two optional methods -
+ *     `response` and `responseError`. Both `response` and `responseError` interceptors get called
+ *     with `http response` object. See {@link ng.$http $http interceptors}.
+ *
+ * @returns {Object} A resource "class" object with methods for the default set of resource actions
+ *   optionally extended with custom `actions`. The default set contains these actions:
+ *
+ *       { 'get':    {method:'GET'},
+ *         'save':   {method:'POST'},
+ *         'query':  {method:'GET', isArray:true},
+ *         'remove': {method:'DELETE'},
+ *         'delete': {method:'DELETE'} };
+ *
+ *   Calling these methods invoke an {@link ng.$http} with the specified http method,
+ *   destination and parameters. When the data is returned from the server then the object is an
+ *   instance of the resource class. The actions `save`, `remove` and `delete` are available on it
+ *   as  methods with the `$` prefix. This allows you to easily perform CRUD operations (create,
+ *   read, update, delete) on server-side data like this:
+ *   <pre>
+        var User = $resource('/user/:userId', {userId:'@id'});
+        var user = User.get({userId:123}, function() {
+          user.abc = true;
+          user.$save();
+        });
+     </pre>
+ *
+ *   It is important to realize that invoking a $resource object method immediately returns an
+ *   empty reference (object or array depending on `isArray`). Once the data is returned from the
+ *   server the existing reference is populated with the actual data. This is a useful trick since
+ *   usually the resource is assigned to a model which is then rendered by the view. Having an empty
+ *   object results in no rendering, once the data arrives from the server then the object is
+ *   populated with the data and the view automatically re-renders itself showing the new data. This
+ *   means that in most cases one never has to write a callback function for the action methods.
+ *
+ *   The action methods on the class object or instance object can be invoked with the following
+ *   parameters:
+ *
+ *   - HTTP GET "class" actions: `Resource.action([parameters], [success], [error])`
+ *   - non-GET "class" actions: `Resource.action([parameters], postData, [success], [error])`
+ *   - non-GET instance actions:  `instance.$action([parameters], [success], [error])`
+ *
+ *   Success callback is called with (value, responseHeaders) arguments. Error callback is called
+ *   with (httpResponse) argument.
+ *
+ *   Class actions return empty instance (with additional properties below).
+ *   Instance actions return promise of the action.
+ *
+ *   The Resource instances and collection have these additional properties:
+ *
+ *   - `$promise`: the {@link ng.$q promise} of the original server interaction that created this
+ *     instance or collection.
+ *
+ *     On success, the promise is resolved with the same resource instance or collection object,
+ *     updated with data from server. This makes it easy to use in
+ *     {@link ngRoute.$routeProvider resolve section of $routeProvider.when()} to defer view
+ *     rendering until the resource(s) are loaded.
+ *
+ *     On failure, the promise is resolved with the {@link ng.$http http response} object, without
+ *     the `resource` property.
+ *
+ *   - `$resolved`: `true` after first server interaction is completed (either with success or
+ *      rejection), `false` before that. Knowing if the Resource has been resolved is useful in
+ *      data-binding.
+ *
+ * @example
+ *
+ * # Credit card resource
+ *
+ * <pre>
+     // Define CreditCard class
+     var CreditCard = $resource('/user/:userId/card/:cardId',
+      {userId:123, cardId:'@id'}, {
+       charge: {method:'POST', params:{charge:true}}
+      });
+
+     // We can retrieve a collection from the server
+     var cards = CreditCard.query(function() {
+       // GET: /user/123/card
+       // server returns: [ {id:456, number:'1234', name:'Smith'} ];
+
+       var card = cards[0];
+       // each item is an instance of CreditCard
+       expect(card instanceof CreditCard).toEqual(true);
+       card.name = "J. Smith";
+       // non GET methods are mapped onto the instances
+       card.$save();
+       // POST: /user/123/card/456 {id:456, number:'1234', name:'J. Smith'}
+       // server returns: {id:456, number:'1234', name: 'J. Smith'};
+
+       // our custom method is mapped as well.
+       card.$charge({amount:9.99});
+       // POST: /user/123/card/456?amount=9.99&charge=true {id:456, number:'1234', name:'J. Smith'}
+     });
+
+     // we can create an instance as well
+     var newCard = new CreditCard({number:'0123'});
+     newCard.name = "Mike Smith";
+     newCard.$save();
+     // POST: /user/123/card {number:'0123', name:'Mike Smith'}
+     // server returns: {id:789, number:'0123', name: 'Mike Smith'};
+     expect(newCard.id).toEqual(789);
+ * </pre>
+ *
+ * The object returned from this function execution is a resource "class" which has "static" method
+ * for each action in the definition.
+ *
+ * Calling these methods invoke `$http` on the `url` template with the given `method`, `params` and
+ * `headers`.
+ * When the data is returned from the server then the object is an instance of the resource type and
+ * all of the non-GET methods are available with `$` prefix. This allows you to easily support CRUD
+ * operations (create, read, update, delete) on server-side data.
+
+   <pre>
+     var User = $resource('/user/:userId', {userId:'@id'});
+     var user = User.get({userId:123}, function() {
+       user.abc = true;
+       user.$save();
+     });
+   </pre>
+ *
+ * It's worth noting that the success callback for `get`, `query` and other methods gets passed
+ * in the response that came from the server as well as $http header getter function, so one
+ * could rewrite the above example and get access to http headers as:
+ *
+   <pre>
+     var User = $resource('/user/:userId', {userId:'@id'});
+     User.get({userId:123}, function(u, getResponseHeaders){
+       u.abc = true;
+       u.$save(function(u, putResponseHeaders) {
+         //u => saved user object
+         //putResponseHeaders => $http header getter
+       });
+     });
+   </pre>
+
+ * # Creating a custom 'PUT' request
+ * In this example we create a custom method on our resource to make a PUT request
+ * <pre>
+ *		var app = angular.module('app', ['ngResource', 'ngRoute']);
+ *
+ *		// Some APIs expect a PUT request in the format URL/object/ID
+ *		// Here we are creating an 'update' method 
+ *		app.factory('Notes', ['$resource', function($resource) {

+ *        {
+ *            'update': { method:'PUT' }
+ *        });
+ *		}]);
+ *
+ *		// In our controller we get the ID from the URL using ngRoute and $routeParams
+ *		// We pass in $routeParams and our Notes factory along with $scope

+   * @ngdoc method
+   * @name ngRoute.$routeProvider#when
+   * @methodOf ngRoute.$routeProvider
+   *
+   * @param {string} path Route path (matched against `$location.path`). If `$location.path`
+   *    contains redundant trailing slash or is missing one, the route will still match and the
+   *    `$location.path` will be updated to add or drop the trailing slash to exactly match the
+   *    route definition.
+   *
+   *      * `path` can contain named groups starting with a colon: e.g. `:name`. All characters up
+   *        to the next slash are matched and stored in `$routeParams` under the given `name`
+   *        when the route matches.
+   *      * `path` can contain named groups starting with a colon and ending with a star:
+   *        e.g.`:name*`. All characters are eagerly stored in `$routeParams` under the given `name`
+   *        when the route matches.
+   *      * `path` can contain optional named groups with a question mark: e.g.`:name?`.
+   *
+   *    For example, routes like `/color/:color/largecode/:largecode*\/edit` will match
+   *    `/color/brown/largecode/code/with/slashs/edit` and extract:
+   *
+   *      * `color: brown`
+   *      * `largecode: code/with/slashs`.
+   *
+   *
+   * @param {Object} route Mapping information to be assigned to `$route.current` on route
+   *    match.
+   *
+   *    Object properties:
+   *
+   *    - `controller` – `{(string|function()=}` – Controller fn that should be associated with
+   *      newly created scope or the name of a {@link angular.Module#controller registered
+   *      controller} if passed as a string.
+   *    - `controllerAs` – `{string=}` – A controller alias name. If present the controller will be
+   *      published to scope under the `controllerAs` name.
+   *    - `template` – `{string=|function()=}` – html template as a string or a function that
+   *      returns an html template as a string which should be used by {@link
+   *      ngRoute.directive:ngView ngView} or {@link ng.directive:ngInclude ngInclude} directives.
+   *      This property takes precedence over `templateUrl`.
+   *
+   *      If `template` is a function, it will be called with the following parameters:
+   *
+   *      - `{Array.<Object>}` - route parameters extracted from the current
+   *        `$location.path()` by applying the current route
+   *
+   *    - `templateUrl` – `{string=|function()=}` – path or function that returns a path to an html
+   *      template that should be used by {@link ngRoute.directive:ngView ngView}.
+   *
+   *      If `templateUrl` is a function, it will be called with the following parameters:
+   *
+   *      - `{Array.<Object>}` - route parameters extracted from the current
+   *        `$location.path()` by applying the current route
+   *
+   *    - `resolve` - `{Object.<string, function>=}` - An optional map of dependencies which should
+   *      be injected into the controller. If any of these dependencies are promises, the router
+   *      will wait for them all to be resolved or one to be rejected before the controller is
+   *      instantiated.
+   *      If all the promises are resolved successfully, the values of the resolved promises are
+   *      injected and {@link ngRoute.$route#$routeChangeSuccess $routeChangeSuccess} event is
+   *      fired. If any of the promises are rejected the
+   *      {@link ngRoute.$route#$routeChangeError $routeChangeError} event is fired. The map object
+   *      is:
+   *
+   *      - `key` – `{string}`: a name of a dependency to be injected into the controller.
+   *      - `factory` - `{string|function}`: If `string` then it is an alias for a service.
+   *        Otherwise if function, then it is {@link api/AUTO.$injector#invoke injected}
+   *        and the return value is treated as the dependency. If the result is a promise, it is
+   *        resolved before its value is injected into the controller. Be aware that
+   *        `ngRoute.$routeParams` will still refer to the previous route within these resolve
+   *        functions.  Use `$route.current.params` to access the new route parameters, instead.
+   *
+   *    - `redirectTo` – {(string|function())=} – value to update
+   *      {@link ng.$location $location} path with and trigger route redirection.
+   *
+   *      If `redirectTo` is a function, it will be called with the following parameters:
+   *
+   *      - `{Object.<string>}` - route parameters extracted from the current
+   *        `$location.path()` by applying the current route templateUrl.
+   *      - `{string}` - current `$location.path()`
+   *      - `{Object}` - current `$location.search()`
+   *
+   *      The custom `redirectTo` function is expected to return a string which will be used
+   *      to update `$location.path()` and `$location.search()`.
+   *
+   *    - `[reloadOnSearch=true]` - {boolean=} - reload route when only `$location.search()`
+   *      or `$location.hash()` changes.
+   *
+   *      If the option is set to `false` and url in the browser changes, then
+   *      `$routeUpdate` event is broadcasted on the root scope.
+   *
+   *    - `[caseInsensitiveMatch=false]` - {boolean=} - match routes without being case sensitive
+   *
+   *      If the option is set to `true`, then the particular route can be matched without being
+   *      case sensitive
+   *

+     * `$route` is used for deep-linking URLs to controllers and views (HTML partials).
+     * It watches `$location.url()` and tries to map the path to an existing route definition.
+     *
+     * Requires the {@link ngRoute `ngRoute`} module to be installed.
+     *
+     * You can define routes through {@link ngRoute.$routeProvider $routeProvider}'s API.
+     *
+     * The `$route` service is typically used in conjunction with the
+     * {@link ngRoute.directive:ngView `ngView`} directive and the
+     * {@link ngRoute.$routeParams `$routeParams`} service.
+     *
+     * @example
+       This example shows how changing the URL hash causes the `$route` to match a route against the
+       URL, and the `ngView` pulls in the partial.
+
+       Note that this example is using {@link ng.directive:script inlined templates}
+       to get it working on jsfiddle as well.

+ * The `$routeParams` service allows you to retrieve the current set of route parameters.
+ *
+ * Requires the {@link ngRoute `ngRoute`} module to be installed.
+ *
+ * The route parameters are a combination of {@link ng.$location `$location`}'s
+ * {@link ng.$location#methods_search `search()`} and {@link ng.$location#methods_path `path()`}.
+ * The `path` parameters are extracted when the {@link ngRoute.$route `$route`} path is matched.
+ *
+ * In case of parameter name collision, `path` params take precedence over `search` params.
+ *
+ * The service guarantees that the identity of the `$routeParams` object will remain unchanged
+ * (but its properties will likely change) even when a route change occurs.
+ *
+ * Note that the `$routeParams` are only updated *after* a route change completes successfully.
+ * This means that you cannot rely on `$routeParams` being correct in route resolve functions.
+ * Instead you can use `$route.current.params` to access the new route's parameters.
+ *
+ * @example
+ * <pre>
+ *  // Given:
+ *  // URL: http://server.com/index.html#/Chapter/1/Section/2?search=moby
+ *  // Route: /Chapter/:chapterId/Section/:sectionId

+/**
+ * @ngdoc directive
+ * @name ngRoute.directive:ngView
+ * @restrict ECA
+ *
+ * @description
+ * # Overview
+ * `ngView` is a directive that complements the {@link ngRoute.$route $route} service by
+ * including the rendered template of the current route into the main layout (`index.html`) file.
+ * Every time the current route changes, the included view changes with it according to the
+ * configuration of the `$route` service.
+ *
+ * Requires the {@link ngRoute `ngRoute`} module to be installed.
+ *
+ * @animations
+ * enter - animation is used to bring new content into the browser.
+ * leave - animation is used to animate existing content away.
+ *
+ * The enter and leave animation occur concurrently.
+ *
+ * @scope
+ * @priority 400
+ * @param {string=} onload Expression to evaluate whenever the view updates.
+ *
+ * @param {string=} autoscroll Whether `ngView` should call {@link ng.$anchorScroll
+ *                  $anchorScroll} to scroll the viewport after the view is updated.
+ *
+ *                  - If the attribute is not set, disable scrolling.
+ *                  - If the attribute is set without value, enable scrolling.
+ *                  - Otherwise enable scrolling only if the `autoscroll` attribute value evaluated
+ *                    as an expression yields a truthy value.

+ *
+ * This object provides a utility for producing rich Error messages within
+ * Angular. It can be called as follows:
+ *
+ * var exampleMinErr = minErr('example');
+ * throw exampleMinErr('one', 'This {0} is {1}', foo, bar);
+ *
+ * The above creates an instance of minErr in the example namespace. The
+ * resulting error will have a namespaced error code of example.one.  The
+ * resulting error will replace {0} with the value of foo, and {1} with the
+ * value of bar. The object is not restricted in the number of arguments it can
+ * take.
+ *
+ * If fewer arguments are specified than necessary for interpolation, the extra
+ * interpolation markers will be preserved in the final string.
+ *
+ * Since data will be parsed statically during a build step, some restrictions

+ *
+ * @description
+ *
+ * Use this directive to **auto-bootstrap** an AngularJS application. The `ngApp` directive
+ * designates the **root element** of the application and is typically placed near the root element
+ * of the page - e.g. on the `<body>` or `<html>` tags.
+ *
+ * Only one AngularJS application can be auto-bootstrapped per HTML document. The first `ngApp`
+ * found in the document will be used to define the root element to auto-bootstrap as an
+ * application. To run multiple applications in an HTML document you must manually bootstrap them using
+ * {@link angular.bootstrap} instead. AngularJS applications cannot be nested within each other.
+ *
+ * You can specify an **AngularJS module** to be used as the root module for the application.  This
+ * module will be loaded into the {@link AUTO.$injector} when the application is bootstrapped and
+ * should contain the application code needed or have dependencies on other modules that will
+ * contain the code. See {@link angular.module} for more information.
+ *
+ * In the example below if the `ngApp` directive were not placed on the `html` element then the
+ * document would not be compiled, the `AppController` would not be instantiated and the `{{ a+b }}`
+ * would not be resolved to `3`.
+ *
+ * `ngApp` is the easiest, and most common, way to bootstrap an application.
+ *
+ <example module="ngAppDemo">
+   <file name="index.html">
+   <div ng-controller="ngAppDemoController">
+     I can add: {{a}} + {{b}} =  {{ a+b }}
+   </div>

+     * The `angular.module` is a global place for creating, registering and retrieving Angular
+     * modules.
+     * All modules (angular core or 3rd party) that should be available to an application must be
+     * registered using this mechanism.
+     *
+     * When passed two or more arguments, a new module is created.  If passed only one argument, an
+     * existing module (the name passed as the first argument to `module`) is retrieved.
+     *
+     *
+     * # Module
+     *
+     * A module is a collection of services, directives, filters, and configuration information.
+     * `angular.module` is used to configure the {@link AUTO.$injector $injector}.
+     *
+     * <pre>
+     * // Create a new module
+     * var myModule = angular.module('myModule', []);
+     *
+     * // register a new service
+     * myModule.value('appName', 'MyCoolApp');
+     *
+     * // configure existing services inside initialization blocks.
+     * myModule.config(function($locationProvider) {
+     *   // Configure existing providers
+     *   $locationProvider.hashPrefix('!');
+     * });
+     * </pre>
+     *
+     * Then you can create an injector and load your modules like this:
+     *
+     * <pre>
+     * var injector = angular.injector(['ng', 'MyModule'])
+     * </pre>
+     *
+     * However it's more likely that you'll just use
+     * {@link ng.directive:ngApp ngApp} or
+     * {@link angular.bootstrap} to simplify this process for you.
+     *
+     * @param {!string} name The name of the module to create or retrieve.
+     * @param {Array.<string>=} requires If specified then new module is being created. If
+     *        unspecified then the the module is being retrieved for further configuration.
+     * @param {Function} configFn Optional configuration function for the module. Same as
+     *        {@link angular.Module#methods_config Module#config()}.
+     * @returns {module} new module with the {@link angular.Module} api.

+/**
+ * @ngdoc function
+ * @name angular.element
+ * @function
+ *
+ * @description
+ * Wraps a raw DOM element or HTML string as a [jQuery](http://jquery.com) element.
+ *
+ * If jQuery is available, `angular.element` is an alias for the
+ * [jQuery](http://api.jquery.com/jQuery/) function. If jQuery is not available, `angular.element`
+ * delegates to Angular's built-in subset of jQuery, called "jQuery lite" or "jqLite."
+ *
+ * <div class="alert alert-success">jqLite is a tiny, API-compatible subset of jQuery that allows
+ * Angular to manipulate the DOM in a cross-browser compatible way. **jqLite** implements only the most
+ * commonly needed functionality with the goal of having a very small footprint.</div>
+ *
+ * To use jQuery, simply load it before `DOMContentLoaded` event fired.
+ *
+ * <div class="alert">**Note:** all element references in Angular are always wrapped with jQuery or
+ * jqLite; they are never raw DOM references.</div>
+ *
+ * ## Angular's jqLite
+ * jqLite provides only the following jQuery methods:
+ *
+ * - [`addClass()`](http://api.jquery.com/addClass/)
+ * - [`after()`](http://api.jquery.com/after/)
+ * - [`append()`](http://api.jquery.com/append/)
+ * - [`attr()`](http://api.jquery.com/attr/)
+ * - [`bind()`](http://api.jquery.com/bind/) - Does not support namespaces, selectors or eventData
+ * - [`children()`](http://api.jquery.com/children/) - Does not support selectors
+ * - [`clone()`](http://api.jquery.com/clone/)
+ * - [`contents()`](http://api.jquery.com/contents/)
+ * - [`css()`](http://api.jquery.com/css/)
+ * - [`data()`](http://api.jquery.com/data/)
+ * - [`empty()`](http://api.jquery.com/empty/)
+ * - [`eq()`](http://api.jquery.com/eq/)
+ * - [`find()`](http://api.jquery.com/find/) - Limited to lookups by tag name
+ * - [`hasClass()`](http://api.jquery.com/hasClass/)
+ * - [`html()`](http://api.jquery.com/html/)
+ * - [`next()`](http://api.jquery.com/next/) - Does not support selectors
+ * - [`on()`](http://api.jquery.com/on/) - Does not support namespaces, selectors or eventData
+ * - [`off()`](http://api.jquery.com/off/) - Does not support namespaces or selectors
+ * - [`one()`](http://api.jquery.com/one/) - Does not support namespaces or selectors
+ * - [`parent()`](http://api.jquery.com/parent/) - Does not support selectors
+ * - [`prepend()`](http://api.jquery.com/prepend/)
+ * - [`prop()`](http://api.jquery.com/prop/)
+ * - [`ready()`](http://api.jquery.com/ready/)
+ * - [`remove()`](http://api.jquery.com/remove/)
+ * - [`removeAttr()`](http://api.jquery.com/removeAttr/)
+ * - [`removeClass()`](http://api.jquery.com/removeClass/)
+ * - [`removeData()`](http://api.jquery.com/removeData/)
+ * - [`replaceWith()`](http://api.jquery.com/replaceWith/)
+ * - [`text()`](http://api.jquery.com/text/)
+ * - [`toggleClass()`](http://api.jquery.com/toggleClass/)
+ * - [`triggerHandler()`](http://api.jquery.com/triggerHandler/) - Passes a dummy event object to handlers.
+ * - [`unbind()`](http://api.jquery.com/unbind/) - Does not support namespaces
+ * - [`val()`](http://api.jquery.com/val/)
+ * - [`wrap()`](http://api.jquery.com/wrap/)
+ *
+ * ## jQuery/jqLite Extras
+ * Angular also provides the following additional methods and events to both jQuery and jqLite:
+ *
+ * ### Events
+ * - `$destroy` - AngularJS intercepts all jqLite/jQuery's DOM destruction apis and fires this event
+ *    on all DOM nodes being removed.  This can be used to clean up any 3rd party bindings to the DOM
+ *    element before it is removed.
+ *
+ * ### Methods
+ * - `controller(name)` - retrieves the controller of the current element or its parent. By default
+ *   retrieves controller associated with the `ngController` directive. If `name` is provided as
+ *   camelCase directive name, then the controller for this directive will be retrieved (e.g.
+ *   `'ngModel'`).
+ * - `injector()` - retrieves the injector of the current element or its parent.
+ * - `scope()` - retrieves the {@link api/ng.$rootScope.Scope scope} of the current
+ *   element or its parent.
+ * - `isolateScope()` - retrieves an isolate {@link api/ng.$rootScope.Scope scope} if one is attached directly to the
+ *   current element. This getter should be used only on elements that contain a directive which starts a new isolate
+ *   scope. Calling `scope()` on this element always returns the original non-isolate scope.
+ * - `inheritedData()` - same as `data()`, but walks up the DOM until a value is found or the top
+ *   parent element is reached.
+ *
+ * @param {string|DOMElement} element HTML string or DOMElement to be wrapped into jQuery.
+ * @returns {Object} jQuery object.

+ * @description

+ *
+ * # Argument names
+ *
+ * The simplest form is to extract the dependencies from the arguments of the function. This is done
+ * by converting the function into a string using `toString()` method and extracting the argument
+ * names.
+ * <pre>
+ *   // Given
+ *   function MyController($scope, $route) {
+ *     // ...
+ *   }
+ *
+ *   // Then
+ *   expect(injector.annotate(MyController)).toEqual(['$scope', '$route']);
+ * </pre>
+ *
+ * This method does not work with code minification / obfuscation. For this reason the following
+ * annotation strategies are supported.
+ *
+ * # The `$inject` property
+ *
+ * If a function has an `$inject` property and its value is an array of strings, then the strings
+ * represent names of services to be injected into the function.
+ * <pre>
+ *   // Given
+ *   var MyController = function(obfuscatedScope, obfuscatedRoute) {
+ *     // ...
+ *   }
+ *   // Define function dependencies
+ *   MyController['$inject'] = ['$scope', '$route'];

+ *   // Then
+ *   expect(injector.annotate(MyController)).toEqual(['$scope', '$route']);
+ * </pre>
+ *
+ * # The array notation
+ *
+ * It is often desirable to inline Injected functions and that's when setting the `$inject` property
+ * is very inconvenient. In these situations using the array notation to specify the dependencies in
+ * a way that survives minification is a better choice:
+ *
+ * <pre>
+ *   // We wish to write this (not minification / obfuscation safe)
+ *   injector.invoke(function($compile, $rootScope) {

+ *     // ...
+ *   };
+ *   tmpFn.$inject = ['$compile', '$rootScope'];
+ *   injector.invoke(tmpFn);
+ *
+ *   // To better support inline function the inline annotation is supported
+ *   injector.invoke(['$compile', '$rootScope', function(obfCompile, obfRootScope) {
+ *     // ...
+ *   }]);
+ *
+ *   // Therefore
+ *   expect(injector.annotate(

+ * with the {@link AUTO.$injector $injector}. Many of these functions are also exposed on
+ * {@link angular.Module}.
+ *
+ * An Angular **service** is a singleton object created by a **service factory**.  These **service
+ * factories** are functions which, in turn, are created by a **service provider**.
+ * The **service providers** are constructor functions. When instantiated they must contain a
+ * property called `$get`, which holds the **service factory** function.
+ *
+ * When you request a service, the {@link AUTO.$injector $injector} is responsible for finding the
+ * correct **service provider**, instantiating it and then calling its `$get` **service factory**
+ * function to get the instance of the **service**.
+ *
+ * Often services have no configuration options and there is no need to add methods to the service
+ * provider.  The provider will be no more than a constructor function with a `$get` property. For
+ * these cases the {@link AUTO.$provide $provide} service has additional helper methods to register
+ * services without specifying a provider.
+ *
+ * * {@link AUTO.$provide#methods_provider provider(provider)} - registers a **service provider** with the
+ *     {@link AUTO.$injector $injector}
+ * * {@link AUTO.$provide#methods_constant constant(obj)} - registers a value/object that can be accessed by
+ *     providers and services.
+ * * {@link AUTO.$provide#methods_value value(obj)} - registers a value/object that can only be accessed by
+ *     services, not providers.
+ * * {@link AUTO.$provide#methods_factory factory(fn)} - registers a service **factory function**, `fn`,
+ *     that will be wrapped in a **service provider** object, whose `$get` property will contain the
+ *     given factory function.
+ * * {@link AUTO.$provide#methods_service service(class)} - registers a **constructor function**, `class` that
+ *     that will be wrapped in a **service provider** object, whose `$get` property will instantiate
+ *      a new object using the given constructor function.
+ *
+ * See the individual methods for more information and examples.

+ * @ngdoc method
+ * @name AUTO.$provide#provider
+ * @methodOf AUTO.$provide
+ * @description
+ *
+ * Register a **provider function** with the {@link AUTO.$injector $injector}. Provider functions
+ * are constructor functions, whose instances are responsible for "providing" a factory for a
+ * service.
+ *
+ * Service provider names start with the name of the service they provide followed by `Provider`.
+ * For example, the {@link ng.$log $log} service has a provider called
+ * {@link ng.$logProvider $logProvider}.
+ *
+ * Service provider objects can have additional methods which allow configuration of the provider
+ * and its service. Importantly, you can configure what kind of service is created by the `$get`
+ * method, or how that service will act. For example, the {@link ng.$logProvider $logProvider} has a
+ * method {@link ng.$logProvider#debugEnabled debugEnabled}
+ * which lets you specify whether the {@link ng.$log $log} service will log debug messages to the
+ * console or not.
+ *
+ * @param {string} name The name of the instance. NOTE: the provider will be available under `name +
+                        'Provider'` key.
+ * @param {(Object|function())} provider If the provider is:
+ *
+ *   - `Object`: then it should have a `$get` method. The `$get` method will be invoked using
+ *     {@link AUTO.$injector#invoke $injector.invoke()} when an instance needs to be created.
+ *   - `Constructor`: a new instance of the provider will be created using                     
+ *     {@link AUTO.$injector#instantiate $injector.instantiate()}, then treated as `object`.
+ *
+ * @returns {Object} registered provider instance
+
+ * @example
+ *
+ * The following example shows how to create a simple event tracking service and register it using
+ * {@link AUTO.$provide#methods_provider $provide.provider()}.
+ *
+ * <pre>
+ *  // Define the eventTracker provider
+ *  function EventTrackerProvider() {
+ *    var trackingUrl = '/track';
+ *
+ *    // A provider method for configuring where the tracked events should been saved
+ *    this.setTrackingUrl = function(url) {
+ *      trackingUrl = url;
+ *    };
+ *
+ *    // The service factory function
+ *    this.$get = ['$http', function($http) {
+ *      var trackedEvents = {};
+ *      return {
+ *        // Call this to track an event
+ *        event: function(event) {
+ *          var count = trackedEvents[event] || 0;
+ *          count += 1;
+ *          trackedEvents[event] = count;
+ *          return count;
+ *        },
+ *        // Call this to save the tracked events to the trackingUrl
+ *        save: function() {
+ *          $http.post(trackingUrl, trackedEvents);
+ *        }
+ *      };
+ *    }];
+ *  }
+ *
+ *  describe('eventTracker', function() {
+ *    var postSpy;
+ *
+ *    beforeEach(module(function($provide) {
+ *      // Register the eventTracker provider
+ *      $provide.provider('eventTracker', EventTrackerProvider);
+ *    }));
+ *
+ *    beforeEach(module(function(eventTrackerProvider) {
+ *      // Configure eventTracker provider
+ *      eventTrackerProvider.setTrackingUrl('/custom-track');
+ *    }));
+ *

+ * ## Comprehensive Directive API
+ *
+ * There are many different options for a directive.
+ *
+ * The difference resides in the return value of the factory function.
+ * You can either return a "Directive Definition Object" (see below) that defines the directive properties,
+ * or just the `postLink` function (all other properties will have the default values).
+ *
+ * <div class="alert alert-success">
+ * **Best Practice:** It's recommended to use the "directive definition object" form.
+ * </div>
+ *
+ * Here's an example directive declared with a Directive Definition Object:
+ *
+ * <pre>
+ *   var myModule = angular.module(...);
+ *
+ *   myModule.directive('directiveName', function factory(injectables) {
+ *     var directiveDefinitionObject = {
+ *       priority: 0,
+ *       template: '<div></div>', // or // function(tElement, tAttrs) { ... },
+ *       // or
+ *       // templateUrl: 'directive.html', // or // function(tElement, tAttrs) { ... },
+ *       replace: false,
+ *       transclude: false,
+ *       restrict: 'A',
+ *       scope: false,
+ *       controller: function($scope, $element, $attrs, $transclude, otherInjectables) { ... },
+ *       require: 'siblingDirectiveName', // or // ['^parentDirectiveName', '?optionalDirectiveName', '?^optionalParent'],
+ *       compile: function compile(tElement, tAttrs, transclude) {
+ *         return {
+ *           pre: function preLink(scope, iElement, iAttrs, controller) { ... },
+ *           post: function postLink(scope, iElement, iAttrs, controller) { ... }
+ *         }
+ *         // or
+ *         // return function postLink( ... ) { ... }
+ *       },
+ *       // or
+ *       // link: {
+ *       //  pre: function preLink(scope, iElement, iAttrs, controller) { ... },
+ *       //  post: function postLink(scope, iElement, iAttrs, controller) { ... }
+ *       // }
+ *       // or
+ *       // link: function postLink( ... ) { ... }
+ *     };
+ *     return directiveDefinitionObject;
+ *   });
+ * </pre>
+ *
+ * <div class="alert alert-warning">
+ * **Note:** Any unspecified options will use the default value. You can see the default values below.
+ * </div>
+ *
+ * Therefore the above can be simplified as:
+ *
+ * <pre>
+ *   var myModule = angular.module(...);
+ *
+ *   myModule.directive('directiveName', function factory(injectables) {
+ *     var directiveDefinitionObject = {
+ *       link: function postLink(scope, iElement, iAttrs) { ... }
+ *     };
+ *     return directiveDefinitionObject;
+ *     // or
+ *     // return function postLink(scope, iElement, iAttrs) { ... }
+ *   });
+ * </pre>
+ *
+ *
+ *
+ * ### Directive Definition Object
+ *
+ * The directive definition object provides instructions to the {@link api/ng.$compile
+ * compiler}. The attributes are:
+ *
+ * #### `priority`
+ * When there are multiple directives defined on a single DOM element, sometimes it
+ * is necessary to specify the order in which the directives are applied. The `priority` is used
+ * to sort the directives before their `compile` functions get called. Priority is defined as a
+ * number. Directives with greater numerical `priority` are compiled first. Pre-link functions
+ * are also run in priority order, but post-link functions are run in reverse order. The order
+ * of directives with the same priority is undefined. The default priority is `0`.
+ *
+ * #### `terminal`
+ * If set to true then the current `priority` will be the last set of directives
+ * which will execute (any directives at the current priority will still execute
+ * as the order of execution on same `priority` is undefined).
+ *
+ * #### `scope`
+ * **If set to `true`,** then a new scope will be created for this directive. If multiple directives on the
+ * same element request a new scope, only one new scope is created. The new scope rule does not
+ * apply for the root of the template since the root of the template always gets a new scope.
+ *
+ * **If set to `{}` (object hash),** then a new "isolate" scope is created. The 'isolate' scope differs from
+ * normal scope in that it does not prototypically inherit from the parent scope. This is useful
+ * when creating reusable components, which should not accidentally read or modify data in the
+ * parent scope.
+ *
+ * The 'isolate' scope takes an object hash which defines a set of local scope properties
+ * derived from the parent scope. These local properties are useful for aliasing values for
+ * templates. Locals definition is a hash of local scope property to its source:
+ *
+ * * `@` or `@attr` - bind a local scope property to the value of DOM attribute. The result is
+ *   always a string since DOM attributes are strings. If no `attr` name is specified  then the
+ *   attribute name is assumed to be the same as the local name.
+ *   Given `<widget my-attr="hello {{name}}">` and widget definition
+ *   of `scope: { localName:'@myAttr' }`, then widget scope property `localName` will reflect
+ *   the interpolated value of `hello {{name}}`. As the `name` attribute changes so will the
+ *   `localName` property on the widget scope. The `name` is read from the parent scope (not
+ *   component scope).
+ *
+ * * `=` or `=attr` - set up bi-directional binding between a local scope property and the
+ *   parent scope property of name defined via the value of the `attr` attribute. If no `attr`
+ *   name is specified then the attribute name is assumed to be the same as the local name.
+ *   Given `<widget my-attr="parentModel">` and widget definition of
+ *   `scope: { localModel:'=myAttr' }`, then widget scope property `localModel` will reflect the
+ *   value of `parentModel` on the parent scope. Any changes to `parentModel` will be reflected
+ *   in `localModel` and any changes in `localModel` will reflect in `parentModel`. If the parent
+ *   scope property doesn't exist, it will throw a NON_ASSIGNABLE_MODEL_EXPRESSION exception. You
+ *   can avoid this behavior using `=?` or `=?attr` in order to flag the property as optional.
+ *
+ * * `&` or `&attr` - provides a way to execute an expression in the context of the parent scope.
+ *   If no `attr` name is specified then the attribute name is assumed to be the same as the
+ *   local name. Given `<widget my-attr="count = count + value">` and widget definition of
+ *   `scope: { localFn:'&myAttr' }`, then isolate scope property `localFn` will point to
+ *   a function wrapper for the `count = count + value` expression. Often it's desirable to
+ *   pass data from the isolated scope via an expression and to the parent scope, this can be
+ *   done by passing a map of local variable names and values into the expression wrapper fn.
+ *   For example, if the expression is `increment(amount)` then we can specify the amount value
+ *   by calling the `localFn` as `localFn({amount: 22})`.
+ *
+ *
+ *
+ * #### `controller`
+ * Controller constructor function. The controller is instantiated before the
+ * pre-linking phase and it is shared with other directives (see
+ * `require` attribute). This allows the directives to communicate with each other and augment
+ * each other's behavior. The controller is injectable (and supports bracket notation) with the following locals:
+ *
+ * * `$scope` - Current scope associated with the element
+ * * `$element` - Current element
+ * * `$attrs` - Current attributes object for the element
+ * * `$transclude` - A transclude linking function pre-bound to the correct transclusion scope.
+ *    The scope can be overridden by an optional first argument.
+ *   `function([scope], cloneLinkingFn)`.
+ *
+ *
+ * #### `require`
+ * Require another directive and inject its controller as the fourth argument to the linking function. The
+ * `require` takes a string name (or array of strings) of the directive(s) to pass in. If an array is used, the
+ * injected argument will be an array in corresponding order. If no such directive can be
+ * found, or if the directive does not have a controller, then an error is raised. The name can be prefixed with:
+ *
+ * * (no prefix) - Locate the required controller on the current element. Throw an error if not found.
+ * * `?` - Attempt to locate the required controller or pass `null` to the `link` fn if not found.
+ * * `^` - Locate the required controller by searching the element's parents. Throw an error if not found.
+ * * `?^` - Attempt to locate the required controller by searching the element's parents or pass `null` to the
+ *   `link` fn if not found.
+ *
+ *
+ * #### `controllerAs`
+ * Controller alias at the directive scope. An alias for the controller so it
+ * can be referenced at the directive template. The directive needs to define a scope for this
+ * configuration to be used. Useful in the case when directive is used as component.
+ *
+ *
+ * #### `restrict`
+ * String of subset of `EACM` which restricts the directive to a specific directive
+ * declaration style. If omitted, the default (attributes only) is used.
+ *
+ * * `E` - Element name: `<my-directive></my-directive>`
+ * * `A` - Attribute (default): `<div my-directive="exp"></div>`
+ * * `C` - Class: `<div class="my-directive: exp;"></div>`
+ * * `M` - Comment: `<!-- directive: my-directive exp -->`
+ *
+ *
+ * #### `template`
+ * replace the current element with the contents of the HTML. The replacement process
+ * migrates all of the attributes / classes from the old element to the new one. See the
+ * {@link guide/directive#creating-custom-directives_creating-directives_template-expanding-directive
+ * Directives Guide} for an example.
+ *
+ * You can specify `template` as a string representing the template or as a function which takes
+ * two arguments `tElement` and `tAttrs` (described in the `compile` function api below) and
+ * returns a string value representing the template.
+ *
+ *
+ * #### `templateUrl`
+ * Same as `template` but the template is loaded from the specified URL. Because
+ * the template loading is asynchronous the compilation/linking is suspended until the template
+ * is loaded.
+ *
+ * You can specify `templateUrl` as a string representing the URL or as a function which takes two
+ * arguments `tElement` and `tAttrs` (described in the `compile` function api below) and returns
+ * a string value representing the url.  In either case, the template URL is passed through {@link
+ * api/ng.$sce#methods_getTrustedResourceUrl $sce.getTrustedResourceUrl}.
+ *
+ *
+ * #### `replace`
+ * specify where the template should be inserted. Defaults to `false`.
+ *
+ * * `true` - the template will replace the current element.
+ * * `false` - the template will replace the contents of the current element.
+ *
+ *
+ * #### `transclude`
+ * compile the content of the element and make it available to the directive.
+ * Typically used with {@link api/ng.directive:ngTransclude
+ * ngTransclude}. The advantage of transclusion is that the linking function receives a
+ * transclusion function which is pre-bound to the correct scope. In a typical setup the widget
+ * creates an `isolate` scope, but the transclusion is not a child, but a sibling of the `isolate`
+ * scope. This makes it possible for the widget to have private state, and the transclusion to
+ * be bound to the parent (pre-`isolate`) scope.
+ *
+ * * `true` - transclude the content of the directive.
+ * * `'element'` - transclude the whole element including any directives defined at lower priority.

+ *   function compile(tElement, tAttrs, transclude) { ... }
+ * </pre>
+ *
+ * The compile function deals with transforming the template DOM. Since most directives do not do
+ * template transformation, it is not used often. Examples that require compile functions are
+ * directives that transform template DOM, such as {@link
+ * api/ng.directive:ngRepeat ngRepeat}, or load the contents
+ * asynchronously, such as {@link api/ngRoute.directive:ngView ngView}. The
+ * compile function takes the following arguments.
+ *
+ *   * `tElement` - template element - The element where the directive has been declared. It is
+ *     safe to do template transformation on the element and child elements only.
+ *
+ *   * `tAttrs` - template attributes - Normalized list of attributes declared on this element shared
+ *     between all directive compile functions.
+ *
+ *   * `transclude` -  [*DEPRECATED*!] A transclude linking function: `function(scope, cloneLinkingFn)`
+ *
+ * <div class="alert alert-warning">
+ * **Note:** The template instance and the link instance may be different objects if the template has
+ * been cloned. For this reason it is **not** safe to do anything other than DOM transformations that
+ * apply to all cloned DOM nodes within the compile function. Specifically, DOM listener registration
+ * should be done in a linking function rather than in a compile function.
+ * </div>
+ *
+ * <div class="alert alert-error">
+ * **Note:** The `transclude` function that is passed to the compile function is deprecated, as it
+ *   e.g. does not know about the right outer scope. Please use the transclude function that is passed
+ *   to the link function instead.
+ * </div>
+
+ * A compile function can have a return value which can be either a function or an object.
+ *
+ * * returning a (post-link) function - is equivalent to registering the linking function via the
+ *   `link` property of the config object when the compile function is empty.
+ *
+ * * returning an object with function(s) registered via `pre` and `post` properties - allows you to
+ *   control when a linking function should be called during the linking phase. See info about
+ *   pre-linking and post-linking functions below.
+ *
+ *
+ * #### `link`
+ * This property is used only if the `compile` property is not defined.
+ *
+ * <pre>
+ *   function link(scope, iElement, iAttrs, controller, transcludeFn) { ... }
+ * </pre>
+ *
+ * The link function is responsible for registering DOM listeners as well as updating the DOM. It is
+ * executed after the template has been cloned. This is where most of the directive logic will be
+ * put.
+ *
+ *   * `scope` - {@link api/ng.$rootScope.Scope Scope} - The scope to be used by the
+ *     directive for registering {@link api/ng.$rootScope.Scope#methods_$watch watches}.
+ *
+ *   * `iElement` - instance element - The element where the directive is to be used. It is safe to
+ *     manipulate the children of the element only in `postLink` function since the children have
+ *     already been linked.
+ *
+ *   * `iAttrs` - instance attributes - Normalized list of attributes declared on this element shared
+ *     between all directive linking functions.
+ *
+ *   * `controller` - a controller instance - A controller instance if at least one directive on the
+ *     element defines a controller. The controller is shared among all the directives, which allows
+ *     the directives to use the controllers as a communication channel.
+ *
+ *   * `transcludeFn` - A transclude linking function pre-bound to the correct transclusion scope.
+ *     The scope can be overridden by an optional first argument. This is the same as the `$transclude`
+ *     parameter of directive controllers.
+ *     `function([scope], cloneLinkingFn)`.
+ *
+ *
+ * #### Pre-linking function
+ *
+ * Executed before the child elements are linked. Not safe to do DOM transformation since the
+ * compiler linking function will fail to locate the correct elements for linking.
+ *
+ * #### Post-linking function
+ *
+ * Executed after the child elements are linked. It is safe to do DOM transformation in the post-linking function.

+ * ### Attributes
+ *
+ * The {@link api/ng.$compile.directive.Attributes Attributes} object - passed as a parameter in the
+ * `link()` or `compile()` functions. It has a variety of uses.
+ *
+ * accessing *Normalized attribute names:*
+ * Directives like 'ngBind' can be expressed in many ways: 'ng:bind', `data-ng-bind`, or 'x-ng-bind'.
+ * the attributes object allows for normalized access to
+ *   the attributes.
+ *
+ * * *Directive inter-communication:* All directives share the same instance of the attributes
+ *   object which allows the directives to use the attributes object as inter directive
+ *   communication.
+ *
+ * * *Supports interpolation:* Interpolation attributes are assigned to the attribute object
+ *   allowing other directives to read the interpolated value.
+ *
+ * * *Observing interpolated attributes:* Use `$observe` to observe the value changes of attributes
+ *   that contain interpolation (e.g. `src="{{bar}}"`). Not only is this very efficient but it's also
+ *   the only way to easily get the actual value because during the linking phase the interpolation
+ *   hasn't been evaluated yet and so the value is at this time set to `undefined`.
+ *
+ * <pre>
+ * function linkingFn(scope, elm, attrs, ctrl) {
+ *   // get the attribute value
+ *   console.log(attrs.ngModel);
+ *
+ *   // change the attribute
+ *   attrs.$set('ngModel', 'new value');
+ *
+ *   // observe changes to interpolated attribute
+ *   attrs.$observe('ngModel', function(value) {
+ *     console.log('ngModel has changed value to ' + value);
+ *   });
+ * }
+ * </pre>
+ *
+ * Below is an example using `$compileProvider`.
+ *
+ * <div class="alert alert-warning">
+ * **Note**: Typically directives are registered with `module.directive`. The example below is
+ * to illustrate how `$compile` works.

+ * @param {number} maxPriority only apply directives lower then given priority (Only effects the
+ *                 root element(s), not their children)
+ * @returns {function(scope[, cloneAttachFn])} a link function which is used to bind template
+ * (a DOM element/tree) to a scope. Where:
+ *
+ *  * `scope` - A {@link ng.$rootScope.Scope Scope} to bind to.
+ *  * `cloneAttachFn` - If `cloneAttachFn` is provided, then the link function will clone the
+ *  `template` and call the `cloneAttachFn` function allowing the caller to attach the
+ *  cloned elements to the DOM document at the appropriate place. The `cloneAttachFn` is
+ *  called as: <br> `cloneAttachFn(clonedElement, scope)` where:
+ *
+ *      * `clonedElement` - is a clone of the original `element` passed into the compiler.
+ *      * `scope` - is the current scope with which the linking function is working with.
+ *
+ * Calling the linking function returns the element of the template. It is either the original
+ * element passed in, or the clone of the element if the `cloneAttachFn` is provided.
+ *
+ * After linking the view is not updated until after a call to $digest which typically is done by
+ * Angular automatically.
+ *
+ * If you need access to the bound view, there are two ways to do it:
+ *
+ * - If you are not asking the linking function to clone the template, create the DOM element(s)
+ *   before you send them to the compiler and keep this reference around.
+ *   <pre>
+ *     var element = $compile('<p>{{total}}</p>')(scope);
+ *   </pre>
+ *
+ * - if on the other hand, you need the element to be cloned, the view reference from the original
+ *   example would not point to the clone, but rather to the original template that was cloned. In
+ *   this case, you can access the clone via the cloneAttachFn:
+ *   <pre>
+ *     var templateElement = angular.element('<p>{{total}}</p>'),
+ *         scope = ....;
+ *
+ *     var clonedElement = $compile(templateElement)(scope, function(clonedElement, scope) {
+ *       //attach the clone to DOM document at the right place
+ *     });
+ *
+ *     //now we have reference to the cloned DOM via `clonedElement`
+ *   </pre>
+ *
+ *
+ * For information on how the compiler works, see the
+ * {@link guide/compiler Angular HTML Compiler} section of the Developer Guide.

+     * @description
+     * The `$http` service is a core Angular service that facilitates communication with the remote
+     * HTTP servers via the browser's {@link https://developer.mozilla.org/en/xmlhttprequest
+     * XMLHttpRequest} object or via {@link http://en.wikipedia.org/wiki/JSONP JSONP}.
+     *
+     * For unit testing applications that use `$http` service, see
+     * {@link ngMock.$httpBackend $httpBackend mock}.
+     *
+     * For a higher level of abstraction, please check out the {@link ngResource.$resource
+     * $resource} service.
+     *
+     * The $http API is based on the {@link ng.$q deferred/promise APIs} exposed by
+     * the $q service. While for simple usage patterns this doesn't matter much, for advanced usage
+     * it is important to familiarize yourself with these APIs and the guarantees they provide.
+     *
+     *
+     * # General usage
+     * The `$http` service is a function which takes a single argument — a configuration object —
+     * that is used to generate an HTTP request and returns  a {@link ng.$q promise}
+     * with two $http specific methods: `success` and `error`.
+     *
+     * <pre>
+     *   $http({method: 'GET', url: '/someUrl'}).
+     *     success(function(data, status, headers, config) {
+     *       // this callback will be called asynchronously
+     *       // when the response is available
+     *     }).
+     *     error(function(data, status, headers, config) {
+     *       // called asynchronously if an error occurs
+     *       // or server returns response with an error status.
+     *     });
+     * </pre>
+     *
+     * Since the returned value of calling the $http function is a `promise`, you can also use
+     * the `then` method to register callbacks, and these callbacks will receive a single argument –
+     * an object representing the response. See the API signature and type info below for more
+     * details.
+     *
+     * A response status code between 200 and 299 is considered a success status and
+     * will result in the success callback being called. Note that if the response is a redirect,
+     * XMLHttpRequest will transparently follow it, meaning that the error callback will not be
+     * called for such responses.
+     *
+     * # Writing Unit Tests that use $http
+     * When unit testing (using {@link api/ngMock ngMock}), it is necessary to call
+     * {@link api/ngMock.$httpBackend#methods_flush $httpBackend.flush()} to flush each pending
+     * request using trained responses.
+     *
+     * ```
+     * $httpBackend.expectGET(...);
+     * $http.get(...);
+     * $httpBackend.flush();
+     * ```
+     *
+     * # Shortcut methods
+     *
+     * Since all invocations of the $http service require passing in an HTTP method and URL, and
+     * POST/PUT requests require request data to be provided as well, shortcut methods
+     * were created:
+     *
+     * <pre>
+     *   $http.get('/someUrl').success(successCallback);
+     *   $http.post('/someUrl', data).success(successCallback);
+     * </pre>
+     *
+     * Complete list of shortcut methods:
+     *
+     * - {@link ng.$http#methods_get $http.get}
+     * - {@link ng.$http#methods_head $http.head}
+     * - {@link ng.$http#methods_post $http.post}
+     * - {@link ng.$http#methods_put $http.put}
+     * - {@link ng.$http#methods_delete $http.delete}
+     * - {@link ng.$http#methods_jsonp $http.jsonp}
+     *
+     *
+     * # Setting HTTP Headers
+     *
+     * The $http service will automatically add certain HTTP headers to all requests. These defaults
+     * can be fully configured by accessing the `$httpProvider.defaults.headers` configuration
+     * object, which currently contains this default configuration:
+     *
+     * - `$httpProvider.defaults.headers.common` (headers that are common for all requests):
+     *   - `Accept: application/json, text/plain, * / *`
+     * - `$httpProvider.defaults.headers.post`: (header defaults for POST requests)
+     *   - `Content-Type: application/json`
+     * - `$httpProvider.defaults.headers.put` (header defaults for PUT requests)
+     *   - `Content-Type: application/json`
+     *
+     * To add or overwrite these defaults, simply add or remove a property from these configuration
+     * objects. To add headers for an HTTP method other than POST or PUT, simply add a new object
+     * with the lowercased HTTP method name as the key, e.g.
+     * `$httpProvider.defaults.headers.get = { 'My-Header' : 'value' }.
+     *
+     * The defaults can also be set at runtime via the `$http.defaults` object in the same
+     * fashion. For example:
+     *
+     * ```
+     * module.run(function($http) {
+     *   $http.defaults.headers.common.Authentication = 'Basic YmVlcDpib29w'
+     * });
+     * ```
+     *
+     * In addition, you can supply a `headers` property in the config object passed when
+     * calling `$http(config)`, which overrides the defaults without changing them globally.
+     *
+     *
+     * # Transforming Requests and Responses
+     *
+     * Both requests and responses can be transformed using transform functions. By default, Angular
+     * applies these transformations:
+     *
+     * Request transformations:
+     *
+     * - If the `data` property of the request configuration object contains an object, serialize it
+     *   into JSON format.
+     *
+     * Response transformations:
+     *
+     *  - If XSRF prefix is detected, strip it (see Security Considerations section below).
+     *  - If JSON response is detected, deserialize it using a JSON parser.
+     *
+     * To globally augment or override the default transforms, modify the
+     * `$httpProvider.defaults.transformRequest` and `$httpProvider.defaults.transformResponse`
+     * properties. These properties are by default an array of transform functions, which allows you
+     * to `push` or `unshift` a new transformation function into the transformation chain. You can
+     * also decide to completely override any default transformations by assigning your
+     * transformation functions to these properties directly without the array wrapper.  These defaults
+     * are again available on the $http factory at run-time, which may be useful if you have run-time
+     * services you wish to be involved in your transformations.
+     *
+     * Similarly, to locally override the request/response transforms, augment the
+     * `transformRequest` and/or `transformResponse` properties of the configuration object passed
+     * into `$http`.
+     *
+     *
+     * # Caching
+     *
+     * To enable caching, set the request configuration `cache` property to `true` (to use default
+     * cache) or to a custom cache object (built with {@link ng.$cacheFactory `$cacheFactory`}).
+     * When the cache is enabled, `$http` stores the response from the server in the specified
+     * cache. The next time the same request is made, the response is served from the cache without
+     * sending a request to the server.
+     *
+     * Note that even if the response is served from cache, delivery of the data is asynchronous in
+     * the same way that real requests are.
+     *
+     * If there are multiple GET requests for the same URL that should be cached using the same
+     * cache, but the cache is not populated yet, only one request to the server will be made and
+     * the remaining requests will be fulfilled using the response from the first request.
+     *
+     * You can change the default cache to a new object (built with
+     * {@link ng.$cacheFactory `$cacheFactory`}) by updating the
+     * {@link ng.$http#properties_defaults `$http.defaults.cache`} property. All requests who set
+     * their `cache` property to `true` will now use this cache object.
+     *
+     * If you set the default cache to `false` then only requests that specify their own custom
+     * cache object will be cached.
+     *
+     * # Interceptors
+     *
+     * Before you start creating interceptors, be sure to understand the
+     * {@link ng.$q $q and deferred/promise APIs}.
+     *
+     * For purposes of global error handling, authentication, or any kind of synchronous or
+     * asynchronous pre-processing of request or postprocessing of responses, it is desirable to be
+     * able to intercept requests before they are handed to the server and
+     * responses before they are handed over to the application code that
+     * initiated these requests. The interceptors leverage the {@link ng.$q
+     * promise APIs} to fulfill this need for both synchronous and asynchronous pre-processing.
+     *
+     * The interceptors are service factories that are registered with the `$httpProvider` by
+     * adding them to the `$httpProvider.interceptors` array. The factory is called and
+     * injected with dependencies (if specified) and returns the interceptor.
+     *
+     * There are two kinds of interceptors (and two kinds of rejection interceptors):
+     *
+     *   * `request`: interceptors get called with http `config` object. The function is free to
+     *     modify the `config` or create a new one. The function needs to return the `config`
+     *     directly or as a promise.
+     *   * `requestError`: interceptor gets called when a previous interceptor threw an error or
+     *     resolved with a rejection.
+     *   * `response`: interceptors get called with http `response` object. The function is free to
+     *     modify the `response` or create a new one. The function needs to return the `response`
+     *     directly or as a promise.
+     *   * `responseError`: interceptor gets called when a previous interceptor threw an error or
+     *     resolved with a rejection.
+     *

+     * # Security Considerations
+     *
+     * When designing web applications, consider security threats from:
+     *
+     * - {@link http://haacked.com/archive/2008/11/20/anatomy-of-a-subtle-json-vulnerability.aspx
+     *   JSON vulnerability}
+     * - {@link http://en.wikipedia.org/wiki/Cross-site_request_forgery XSRF}
+     *
+     * Both server and the client must cooperate in order to eliminate these threats. Angular comes
+     * pre-configured with strategies that address these issues, but for this to work backend server
+     * cooperation is required.
+     *
+     * ## JSON Vulnerability Protection
+     *
+     * A {@link http://haacked.com/archive/2008/11/20/anatomy-of-a-subtle-json-vulnerability.aspx
+     * JSON vulnerability} allows third party website to turn your JSON resource URL into
+     * {@link http://en.wikipedia.org/wiki/JSONP JSONP} request under some conditions. To
+     * counter this your server can prefix all JSON requests with following string `")]}',\n"`.
+     * Angular will automatically strip the prefix before processing it as JSON.
+     *
+     * For example if your server needs to return:
+     * <pre>
+     * ['one','two']
+     * </pre>
+     *
+     * which is vulnerable to attack, your server can return:
+     * <pre>
+     * )]}',
+     * ['one','two']
+     * </pre>
+     *
+     * Angular will strip the prefix, before processing the JSON.
+     *
+     *
+     * ## Cross Site Request Forgery (XSRF) Protection
+     *
+     * {@link http://en.wikipedia.org/wiki/Cross-site_request_forgery XSRF} is a technique by which
+     * an unauthorized site can gain your user's private data. Angular provides a mechanism
+     * to counter XSRF. When performing XHR requests, the $http service reads a token from a cookie
+     * (by default, `XSRF-TOKEN`) and sets it as an HTTP header (`X-XSRF-TOKEN`). Since only
+     * JavaScript that runs on your domain could read the cookie, your server can be assured that
+     * the XHR came from JavaScript running on your domain. The header will not be set for
+     * cross-domain requests.
+     *
+     * To take advantage of this, your server needs to set a token in a JavaScript readable session
+     * cookie called `XSRF-TOKEN` on the first HTTP GET request. On subsequent XHR requests the
+     * server can verify that the cookie matches `X-XSRF-TOKEN` HTTP header, and therefore be sure
+     * that only JavaScript running on your domain could have sent the request. The token must be
+     * unique for each user and must be verifiable by the server (to prevent the JavaScript from
+     * making up its own tokens). We recommend that the token is a digest of your site's
+     * authentication cookie with a {@link https://en.wikipedia.org/wiki/Salt_(cryptography) salt}
+     * for added security.
+     *
+     * The name of the headers can be specified using the xsrfHeaderName and xsrfCookieName
+     * properties of either $httpProvider.defaults at config-time, $http.defaults at run-time,
+     * or the per-request config object.
+     *
+     *
+     * @param {object} config Object describing the request to be made and how it should be
+     *    processed. The object has following properties:
+     *
+     *    - **method** – `{string}` – HTTP method (e.g. 'GET', 'POST', etc)
+     *    - **url** – `{string}` – Absolute or relative URL of the resource that is being requested.
+     *    - **params** – `{Object.<string|Object>}` – Map of strings or objects which will be turned
+     *      to `?key1=value1&key2=value2` after the url. If the value is not a string, it will be
+     *      JSONified.
+     *    - **data** – `{string|Object}` – Data to be sent as the request message data.
+     *    - **headers** – `{Object}` – Map of strings or functions which return strings representing
+     *      HTTP headers to send to the server. If the return value of a function is null, the
+     *      header will not be sent.
+     *    - **xsrfHeaderName** – `{string}` – Name of HTTP header to populate with the XSRF token.
+     *    - **xsrfCookieName** – `{string}` – Name of cookie containing the XSRF token.
+     *    - **transformRequest** –
+     *      `{function(data, headersGetter)|Array.<function(data, headersGetter)>}` –
+     *      transform function or an array of such functions. The transform function takes the http
+     *      request body and headers and returns its transformed (typically serialized) version.
+     *    - **transformResponse** –
+     *      `{function(data, headersGetter)|Array.<function(data, headersGetter)>}` –
+     *      transform function or an array of such functions. The transform function takes the http
+     *      response body and headers and returns its transformed (typically deserialized) version.
+     *    - **cache** – `{boolean|Cache}` – If true, a default $http cache will be used to cache the
+     *      GET request, otherwise if a cache instance built with
+     *      {@link ng.$cacheFactory $cacheFactory}, this cache will be used for
+     *      caching.
+     *    - **timeout** – `{number|Promise}` – timeout in milliseconds, or {@link ng.$q promise}
+     *      that should abort the request when resolved.
+     *    - **withCredentials** - `{boolean}` - whether to to set the `withCredentials` flag on the
+     *      XHR object. See {@link https://developer.mozilla.org/en/http_access_control#section_5
+     *      requests with credentials} for more information.
+     *    - **responseType** - `{string}` - see {@link
+     *      https://developer.mozilla.org/en-US/docs/DOM/XMLHttpRequest#responseType requestType}.
+     *
+     * @returns {HttpPromise} Returns a {@link ng.$q promise} object with the
+     *   standard `then` method and two http specific methods: `success` and `error`. The `then`
+     *   method takes two arguments a success and an error callback which will be called with a
+     *   response object. The `success` and `error` methods take a single argument - a function that
+     *   will be called when the request succeeds or fails respectively. The arguments passed into
+     *   these functions are destructured representation of the response object passed into the
+     *   `then` method. The response object has these properties:
+     *
+     *   - **data** – `{string|Object}` – The response body transformed with the transform
+     *     functions.
+     *   - **status** – `{number}` – HTTP status code of the response.
+     *   - **headers** – `{function([headerName])}` – Header getter function.
+     *   - **config** – `{Object}` – The configuration object that was used to generate the request.
+     *
+     * @property {Array.<Object>} pendingRequests Array of config objects for currently pending
+     *   requests. This is primarily meant to be used for debugging purposes.

+// Sandboxing Angular Expressions
+// ------------------------------
+// Angular expressions are generally considered safe because these expressions only have direct
+// access to $scope and locals. However, one can obtain the ability to execute arbitrary JS code by
+// obtaining a reference to native JS functions such as the Function constructor.
+//
+// As an example, consider the following Angular expression:
+//
+//   {}.toString.constructor(alert("evil JS code"))
+//
+// We want to prevent this type of access. For the sake of performance, during the lexing phase we
+// disallow any "dotted" access to any member named "constructor".
+//
+// For reflective calls (a[b]) we check that the value of the lookup is not the Function constructor
+// while evaluating the expression, which is a stronger but more expensive test. Since reflective
+// calls are expensive anyway, this is not such a big deal compared to static dereferencing.
+//
+// This sandboxing technique is not perfect and doesn't aim to be. The goal is to prevent exploits
+// against the expression language, but not to prevent exploits that were enabled by exposing
+// sensitive JavaScript or browser apis on Scope. Exposing such objects on a Scope is never a good
+// practice and therefore we are not even trying to protect against interaction with an object
+// explicitly exposed in this way.
+//
+// A developer could foil the name check by aliasing the Function constructor under a different
+// name on the scope.
+//
+// In general, it is not possible to access a Window object from an angular expression unless a
+// window or some DOM object that has a reference to window is published onto a Scope.

+   * @description
+   *
+   * **This feature is deprecated, see deprecation notes below for more info**
+   *
+   * If set to true (default is false), $parse will unwrap promises automatically when a promise is
+   * found at any part of the expression. In other words, if set to true, the expression will always
+   * result in a non-promise value.
+   *
+   * While the promise is unresolved, it's treated as undefined, but once resolved and fulfilled,
+   * the fulfillment value is used in place of the promise while evaluating the expression.
+   *
+   * **Deprecation notice**
+   *
+   * This is a feature that didn't prove to be wildly useful or popular, primarily because of the
+   * dichotomy between data access in templates (accessed as raw values) and controller code
+   * (accessed as promises).
+   *
+   * In most code we ended up resolving promises manually in controllers anyway and thus unifying
+   * the model access there.
+   *
+   * Other downsides of automatic promise unwrapping:
+   *
+   * - when building components it's often desirable to receive the raw promises
+   * - adds complexity and slows down expression evaluation
+   * - makes expression code pre-generation unattractive due to the amount of code that needs to be
+   *   generated
+   * - makes IDE auto-completion and tool support hard
+   *
+   * **Warning Logs**
+   *
+   * If the unwrapping is enabled, Angular will log a warning about each expression that unwraps a
+   * promise (to reduce the noise, each expression is logged only once). To disable this logging use
+   * `$parseProvider.logPromiseWarnings(false)` api.

+ * @ngdoc service
+ * @name ng.$q
+ * @requires $rootScope
+ *
+ * @description
+ * A promise/deferred implementation inspired by [Kris Kowal's Q](https://github.com/kriskowal/q).
+ *
+ * [The CommonJS Promise proposal](http://wiki.commonjs.org/wiki/Promises) describes a promise as an
+ * interface for interacting with an object that represents the result of an action that is
+ * performed asynchronously, and may or may not be finished at any given point in time.
+ *
+ * From the perspective of dealing with error handling, deferred and promise APIs are to
+ * asynchronous programming what `try`, `catch` and `throw` keywords are to synchronous programming.
+ *
+ * <pre>
+ *   // for the purpose of this example let's assume that variables `$q`, `scope` and `okToGreet`
+ *   // are available in the current lexical scope (they could have been injected or passed in).
+ * 
+ *   function asyncGreet(name) {
+ *     var deferred = $q.defer();
+ *
+ *     setTimeout(function() {
+ *       // since this fn executes async in a future turn of the event loop, we need to wrap
+ *       // our code into an $apply call so that the model changes are properly observed.
+ *       scope.$apply(function() {
+ *         deferred.notify('About to greet ' + name + '.');
+ *
+ *         if (okToGreet(name)) {
+ *           deferred.resolve('Hello, ' + name + '!');
+ *         } else {
+ *           deferred.reject('Greeting ' + name + ' is not allowed.');
+ *         }
+ *       });
+ *     }, 1000);
+ *
+ *     return deferred.promise;
+ *   }
+ *
+ *   var promise = asyncGreet('Robin Hood');
+ *   promise.then(function(greeting) {
+ *     alert('Success: ' + greeting);
+ *   }, function(reason) {
+ *     alert('Failed: ' + reason);
+ *   }, function(update) {
+ *     alert('Got notification: ' + update);
+ *   });
+ * </pre>
+ *
+ * At first it might not be obvious why this extra complexity is worth the trouble. The payoff
+ * comes in the way of guarantees that promise and deferred APIs make, see
+ * https://github.com/kriskowal/uncommonjs/blob/master/promises/specification.md.
+ *
+ * Additionally the promise api allows for composition that is very hard to do with the
+ * traditional callback ([CPS](http://en.wikipedia.org/wiki/Continuation-passing_style)) approach.
+ * For more on this please see the [Q documentation](https://github.com/kriskowal/q) especially the
+ * section on serial or parallel joining of promises.
+ *
+ *
+ * # The Deferred API
+ *
+ * A new instance of deferred is constructed by calling `$q.defer()`.
+ *
+ * The purpose of the deferred object is to expose the associated Promise instance as well as APIs
+ * that can be used for signaling the successful or unsuccessful completion, as well as the status
+ * of the task.
+ *
+ * **Methods**
+ *
+ * - `resolve(value)` – resolves the derived promise with the `value`. If the value is a rejection
+ *   constructed via `$q.reject`, the promise will be rejected instead.
+ * - `reject(reason)` – rejects the derived promise with the `reason`. This is equivalent to
+ *   resolving it with a rejection constructed via `$q.reject`.
+ * - `notify(value)` - provides updates on the status of the promise's execution. This may be called
+ *   multiple times before the promise is either resolved or rejected.
+ *
+ * **Properties**
+ *
+ * - promise – `{Promise}` – promise object associated with this deferred.
+ *
+ *
+ * # The Promise API
+ *
+ * A new promise instance is created when a deferred instance is created and can be retrieved by
+ * calling `deferred.promise`.
+ *
+ * The purpose of the promise object is to allow for interested parties to get access to the result
+ * of the deferred task when it completes.
+ *
+ * **Methods**
+ *
+ * - `then(successCallback, errorCallback, notifyCallback)` – regardless of when the promise was or
+ *   will be resolved or rejected, `then` calls one of the success or error callbacks asynchronously
+ *   as soon as the result is available. The callbacks are called with a single argument: the result
+ *   or rejection reason. Additionally, the notify callback may be called zero or more times to
+ *   provide a progress indication, before the promise is resolved or rejected.
+ *
+ *   This method *returns a new promise* which is resolved or rejected via the return value of the
+ *   `successCallback`, `errorCallback`. It also notifies via the return value of the
+ *   `notifyCallback` method. The promise can not be resolved or rejected from the notifyCallback
+ *   method.
+ *
+ * - `catch(errorCallback)` – shorthand for `promise.then(null, errorCallback)`
+ *
+ * - `finally(callback)` – allows you to observe either the fulfillment or rejection of a promise,
+ *   but to do so without modifying the final value. This is useful to release resources or do some
+ *   clean-up that needs to be done whether the promise was rejected or resolved. See the [full
+ *   specification](https://github.com/kriskowal/q/wiki/API-Reference#promisefinallycallback) for
+ *   more information.
+ *
+ *   Because `finally` is a reserved word in JavaScript and reserved keywords are not supported as
+ *   property names by ES3, you'll need to invoke the method like `promise['finally'](callback)` to
+ *   make your code IE8 compatible.
+ *
+ * # Chaining promises
+ *
+ * Because calling the `then` method of a promise returns a new derived promise, it is easily
+ * possible to create a chain of promises:
+ *
+ * <pre>
+ *   promiseB = promiseA.then(function(result) {
+ *     return result + 1;
+ *   });
+ *
+ *   // promiseB will be resolved immediately after promiseA is resolved and its value
+ *   // will be the result of promiseA incremented by 1
+ * </pre>
+ *
+ * It is possible to create chains of any length and since a promise can be resolved with another
+ * promise (which will defer its resolution further), it is possible to pause/defer resolution of
+ * the promises at any point in the chain. This makes it possible to implement powerful APIs like
+ * $http's response interceptors.
+ *
+ *
+ * # Differences between Kris Kowal's Q and $q
+ *
+ *  There are two main differences:
+ *
+ * - $q is integrated with the {@link ng.$rootScope.Scope} Scope model observation
+ *   mechanism in angular, which means faster propagation of resolution or rejection into your
+ *   models and avoiding unnecessary browser repaints, which would result in flickering UI.
+ * - Q has many more features than $q, but that comes at a cost of bytes. $q is tiny, but contains
+ *   all the important functionality needed for common async tasks.
+ *
+ *  # Testing
+ *
+ *  <pre>
+ *    it('should simulate promise', inject(function($q, $rootScope) {
+ *      var deferred = $q.defer();
+ *      var promise = deferred.promise;
+ *      var resolvedValue;
+ *
+ *      promise.then(function(value) { resolvedValue = value; });
+ *      expect(resolvedValue).toBeUndefined();
+ *
+ *      // Simulate resolving of promise
+ *      deferred.resolve(123);
+ *      // Note that the 'then' function does not get called synchronously.
+ *      // This is because we want the promise API to always be async, whether or not
+ *      // it got called synchronously or asynchronously.
+ *      expect(resolvedValue).toBeUndefined();
+ *
+ *      // Propagate promise resolution to 'then' functions using $apply().
+ *      $rootScope.$apply();
+ *      expect(resolvedValue).toEqual(123);
+ *    }));
+ *  </pre>

+ * DESIGN NOTES
+ *
+ * The design decisions behind the scope are heavily favored for speed and memory consumption.
+ *
+ * The typical use of scope is to watch the expressions, which most of the time return the same
+ * value as last time so we optimize the operation.
+ *
+ * Closures construction is expensive in terms of speed as well as memory:
+ *   - No closures, instead use prototypical inheritance for API
+ *   - Internal state needs to be stored on scope directly, which means that private state is
+ *     exposed as $$____ properties
+ *
+ * Loop operations are optimized by using while(count--) { ... }
+ *   - this means that in order to keep the same order of execution as addition we have to add
+ *     items to the array at the beginning (shift) instead of at the end (push)
+ *
+ * Child scopes are created and removed often
+ *   - Using an array would be slow since inserts in middle are expensive so we use linked list
+ *
+ * There are few watches then a lot of observers. This is why you don't want the observer to be
+ * implemented in the same way as watch. Watch requires return of initialization function which
+ * are expensive to construct.

+       *
+       * @description
+       * Registers a `listener` callback to be executed whenever the `watchExpression` changes.
+       *
+       * - The `watchExpression` is called on every call to {@link ng.$rootScope.Scope#methods_$digest
+       *   $digest()} and should return the value that will be watched. (Since
+       *   {@link ng.$rootScope.Scope#methods_$digest $digest()} reruns when it detects changes the
+       *   `watchExpression` can execute multiple times per
+       *   {@link ng.$rootScope.Scope#methods_$digest $digest()} and should be idempotent.)
+       * - The `listener` is called only when the value from the current `watchExpression` and the
+       *   previous call to `watchExpression` are not equal (with the exception of the initial run,
+       *   see below). The inequality is determined according to
+       *   {@link angular.equals} function. To save the value of the object for later comparison,
+       *   the {@link angular.copy} function is used. It also means that watching complex options
+       *   will have adverse memory and performance implications.
+       * - The watch `listener` may change the model, which may trigger other `listener`s to fire.
+       *   This is achieved by rerunning the watchers until no changes are detected. The rerun
+       *   iteration limit is 10 to prevent an infinite loop deadlock.
+       *
+       *
+       * If you want to be notified whenever {@link ng.$rootScope.Scope#methods_$digest $digest} is called,
+       * you can register a `watchExpression` function with no `listener`. (Since `watchExpression`
+       * can execute multiple times per {@link ng.$rootScope.Scope#methods_$digest $digest} cycle when a
+       * change is detected, be prepared for multiple calls to your listener.)
+       *
+       * After a watcher is registered with the scope, the `listener` fn is called asynchronously
+       * (via {@link ng.$rootScope.Scope#methods_$evalAsync $evalAsync}) to initialize the
+       * watcher. In rare cases, this is undesirable because the listener is called when the result
+       * of `watchExpression` didn't change. To detect this scenario within the `listener` fn, you
+       * can compare the `newVal` and `oldVal`. If these two values are identical (`===`) then the
+       * listener was called due to initialization.
+       *
+       * The example below contains an illustration of using a function as your $watch listener
+       *
+       *
+       * # Example
+       * <pre>

+       * the model, the `$digest()` keeps calling the {@link ng.$rootScope.Scope#methods_$watch watchers}
+       * until no more listeners are firing. This means that it is possible to get into an infinite
+       * loop. This function will throw `'Maximum iteration limit exceeded.'` if the number of
+       * iterations exceeds 10.
+       *
+       * Usually, you don't call `$digest()` directly in
+       * {@link ng.directive:ngController controllers} or in
+       * {@link ng.$compileProvider#methods_directive directives}.
+       * Instead, you should call {@link ng.$rootScope.Scope#methods_$apply $apply()} (typically from within
+       * a {@link ng.$compileProvider#methods_directive directives}), which will force a `$digest()`.
+       *
+       * If you want to be notified whenever `$digest()` is called,
+       * you can register a `watchExpression` function with
+       * {@link ng.$rootScope.Scope#methods_$watch $watch()} with no `listener`.
+       *
+       * In unit tests, you may need to call `$digest()` to simulate the scope life cycle.

+ * `$sceDelegate` is a service that is used by the `$sce` service to provide {@link ng.$sce Strict

+ *
+ * Typically, you would configure or override the {@link ng.$sceDelegate $sceDelegate} instead of
+ * the `$sce` service to customize the way Strict Contextual Escaping works in AngularJS.  This is
+ * because, while the `$sce` provides numerous shorthand methods, etc., you really only need to

+ * work because `$sce` delegates to `$sceDelegate` for these operations.
+ *
+ * Refer {@link ng.$sceDelegateProvider $sceDelegateProvider} to configure this service.
+ *
+ * The default instance of `$sceDelegate` should work out of the box with little pain.  While you
+ * can override it completely to change the behavior of `$sce`, the common case would
+ * involve configuring the {@link ng.$sceDelegateProvider $sceDelegateProvider} instead by setting

+ *
+ * - your app is hosted at url `http://myapp.example.com/`

+ * - and you have an open redirect at `http://myapp.example.com/clickThru?...`.

+ * <pre class="prettyprint">

+ * @function
+ *
+ * @description
+ *
+ * `$sce` is a service that provides Strict Contextual Escaping services to AngularJS.
+ *
+ * # Strict Contextual Escaping
+ *
+ * Strict Contextual Escaping (SCE) is a mode in which AngularJS requires bindings in certain
+ * contexts to result in a value that is marked as safe to use for that context.  One example of
+ * such a context is binding arbitrary html controlled by the user via `ng-bind-html`.  We refer
+ * to these contexts as privileged or SCE contexts.
+ *
+ * As of version 1.2, Angular ships with SCE enabled by default.
+ *
+ * Note:  When enabled (the default), IE8 in quirks mode is not supported.  In this mode, IE8 allows
+ * one to execute arbitrary javascript by the use of the expression() syntax.  Refer
+ * <http://blogs.msdn.com/b/ie/archive/2008/10/16/ending-expressions.aspx> to learn more about them.
+ * You can ensure your document is in standards mode and not quirks mode by adding `<!doctype html>`
+ * to the top of your HTML document.
+ *
+ * SCE assists in writing code in way that (a) is secure by default and (b) makes auditing for
+ * security vulnerabilities such as XSS, clickjacking, etc. a lot easier.
+ *
+ * Here's an example of a binding in a privileged context:
+ *
+ * <pre class="prettyprint">
+ *     <input ng-model="userHtml">
+ *     <div ng-bind-html="userHtml">
+ * </pre>
+ *
+ * Notice that `ng-bind-html` is bound to `userHtml` controlled by the user.  With SCE
+ * disabled, this application allows the user to render arbitrary HTML into the DIV.
+ * In a more realistic example, one may be rendering user comments, blog articles, etc. via
+ * bindings.  (HTML is just one example of a context where rendering user controlled input creates
+ * security vulnerabilities.)
+ *
+ * For the case of HTML, you might use a library, either on the client side, or on the server side,
+ * to sanitize unsafe HTML before binding to the value and rendering it in the document.
+ *
+ * How would you ensure that every place that used these types of bindings was bound to a value that
+ * was sanitized by your library (or returned as safe for rendering by your server?)  How can you
+ * ensure that you didn't accidentally delete the line that sanitized the value, or renamed some
+ * properties/fields and forgot to update the binding to the sanitized value?
+ *
+ * To be secure by default, you want to ensure that any such bindings are disallowed unless you can
+ * determine that something explicitly says it's safe to use a value for binding in that
+ * context.  You can then audit your code (a simple grep would do) to ensure that this is only done
+ * for those values that you can easily tell are safe - because they were received from your server,
+ * sanitized by your library, etc.  You can organize your codebase to help with this - perhaps
+ * allowing only the files in a specific directory to do this.  Ensuring that the internal API
+ * exposed by that code doesn't markup arbitrary values as safe then becomes a more manageable task.
+ *
+ * In the case of AngularJS' SCE service, one uses {@link ng.$sce#methods_trustAs $sce.trustAs} 
+ * (and shorthand methods such as {@link ng.$sce#methods_trustAsHtml $sce.trustAsHtml}, etc.) to
+ * obtain values that will be accepted by SCE / privileged contexts.
+ *
+ *
+ * ## How does it work?
+ *
+ * In privileged contexts, directives and code will bind to the result of {@link ng.$sce#methods_getTrusted
+ * $sce.getTrusted(context, value)} rather than to the value directly.  Directives use {@link
+ * ng.$sce#methods_parse $sce.parseAs} rather than `$parse` to watch attribute bindings, which performs the
+ * {@link ng.$sce#methods_getTrusted $sce.getTrusted} behind the scenes on non-constant literals.
+ *
+ * As an example, {@link ng.directive:ngBindHtml ngBindHtml} uses {@link
+ * ng.$sce#methods_parseAsHtml $sce.parseAsHtml(binding expression)}.  Here's the actual code (slightly
+ * simplified):
+ *
+ * <pre class="prettyprint">
+ *   var ngBindHtmlDirective = ['$sce', function($sce) {
+ *     return function(scope, element, attr) {
+ *       scope.$watch($sce.parseAsHtml(attr.ngBindHtml), function(value) {
+ *         element.html(value || '');
+ *       });
+ *     };
+ *   }];
+ * </pre>
+ *
+ * ## Impact on loading templates
+ *
+ * This applies both to the {@link ng.directive:ngInclude `ng-include`} directive as well as
+ * `templateUrl`'s specified by {@link guide/directive directives}.
+ *
+ * By default, Angular only loads templates from the same domain and protocol as the application
+ * document.  This is done by calling {@link ng.$sce#methods_getTrustedResourceUrl
+ * $sce.getTrustedResourceUrl} on the template URL.  To load templates from other domains and/or
+ * protocols, you may either either {@link ng.$sceDelegateProvider#methods_resourceUrlWhitelist whitelist
+ * them} or {@link ng.$sce#methods_trustAsResourceUrl wrap it} into a trusted value.
+ *
+ * *Please note*:
+ * The browser's
+ * {@link https://code.google.com/p/browsersec/wiki/Part2#Same-origin_policy_for_XMLHttpRequest
+ * Same Origin Policy} and {@link http://www.w3.org/TR/cors/ Cross-Origin Resource Sharing (CORS)}
+ * policy apply in addition to this and may further restrict whether the template is successfully
+ * loaded.  This means that without the right CORS policy, loading templates from a different domain
+ * won't work on all browsers.  Also, loading templates from `file://` URL does not work on some
+ * browsers.
+ *
+ * ## This feels like too much overhead for the developer?
+ *
+ * It's important to remember that SCE only applies to interpolation expressions.
+ *
+ * If your expressions are constant literals, they're automatically trusted and you don't need to
+ * call `$sce.trustAs` on them (remember to include the `ngSanitize` module) (e.g.
+ * `<div ng-bind-html="'<b>implicitly trusted</b>'"></div>`) just works.
+ *
+ * Additionally, `a[href]` and `img[src]` automatically sanitize their URLs and do not pass them
+ * through {@link ng.$sce#methods_getTrusted $sce.getTrusted}.  SCE doesn't play a role here.
+ *
+ * The included {@link ng.$sceDelegate $sceDelegate} comes with sane defaults to allow you to load
+ * templates in `ng-include` from your application's domain without having to even know about SCE.
+ * It blocks loading templates from other domains or loading templates over http from an https
+ * served document.  You can change these by setting your own custom {@link
+ * ng.$sceDelegateProvider#methods_resourceUrlWhitelist whitelists} and {@link
+ * ng.$sceDelegateProvider#methods_resourceUrlBlacklist blacklists} for matching such URLs.
+ *
+ * This significantly reduces the overhead.  It is far easier to pay the small overhead and have an
+ * application that's secure and can be audited to verify that with much more ease than bolting
+ * security onto an application later.
+ *
+ * <a name="contexts"></a>
+ * ## What trusted context types are supported?
+ *
+ * | Context             | Notes          |
+ * |---------------------|----------------|
+ * | `$sce.HTML`         | For HTML that's safe to source into the application.  The {@link ng.directive:ngBindHtml ngBindHtml} directive uses this context for bindings. |
+ * | `$sce.CSS`          | For CSS that's safe to source into the application.  Currently unused.  Feel free to use it in your own directives. |
+ * | `$sce.URL`          | For URLs that are safe to follow as links.  Currently unused (`<a href=` and `<img src=` sanitize their urls and don't consititute an SCE context. |
+ * | `$sce.RESOURCE_URL` | For URLs that are not only safe to follow as links, but whose contens are also safe to include in your application.  Examples include `ng-include`, `src` / `ngSrc` bindings for tags other than `IMG` (e.g. `IFRAME`, `OBJECT`, etc.)  <br><br>Note that `$sce.RESOURCE_URL` makes a stronger statement about the URL than `$sce.URL` does and therefore contexts requiring values trusted for `$sce.RESOURCE_URL` can be used anywhere that values trusted for `$sce.URL` are required. |
+ * | `$sce.JS`           | For JavaScript that is safe to execute in your application's context.  Currently unused.  Feel free to use it in your own directives. |
+ *
+ * ## Format of items in {@link ng.$sceDelegateProvider#methods_resourceUrlWhitelist resourceUrlWhitelist}/{@link ng.$sceDelegateProvider#methods_resourceUrlBlacklist Blacklist} <a name="resourceUrlPatternItem"></a>
+ *
+ *  Each element in these arrays must be one of the following:
+ *
+ *  - **'self'**
+ *    - The special **string**, `'self'`, can be used to match against all URLs of the **same
+ *      domain** as the application document using the **same protocol**.
+ *  - **String** (except the special value `'self'`)
+ *    - The string is matched against the full *normalized / absolute URL* of the resource
+ *      being tested (substring matches are not good enough.)
+ *    - There are exactly **two wildcard sequences** - `*` and `**`.  All other characters
+ *      match themselves.
+ *    - `*`: matches zero or more occurances of any character other than one of the following 6
+ *      characters: '`:`', '`/`', '`.`', '`?`', '`&`' and ';'.  It's a useful wildcard for use
+ *      in a whitelist.
+ *    - `**`: matches zero or more occurances of *any* character.  As such, it's not
+ *      not appropriate to use in for a scheme, domain, etc. as it would match too much.  (e.g.
+ *      http://**.example.com/ would match http://evil.com/?ignore=.example.com/ and that might
+ *      not have been the intention.)  It's usage at the very end of the path is ok.  (e.g.
+ *      http://foo.example.com/templates/**).
+ *  - **RegExp** (*see caveat below*)
+ *    - *Caveat*:  While regular expressions are powerful and offer great flexibility,  their syntax
+ *      (and all the inevitable escaping) makes them *harder to maintain*.  It's easy to
+ *      accidentally introduce a bug when one updates a complex expression (imho, all regexes should
+ *      have good test coverage.).  For instance, the use of `.` in the regex is correct only in a
+ *      small number of cases.  A `.` character in the regex used when matching the scheme or a
+ *      subdomain could be matched against a `:` or literal `.` that was likely not intended.   It
+ *      is highly recommended to use the string patterns and only fall back to regular expressions
+ *      if they as a last resort.
+ *    - The regular expression must be an instance of RegExp (i.e. not a string.)  It is
+ *      matched against the **entire** *normalized / absolute URL* of the resource being tested
+ *      (even when the RegExp did not have the `^` and `$` codes.)  In addition, any flags
+ *      present on the RegExp (such as multiline, global, ignoreCase) are ignored.
+ *    - If you are generating your JavaScript from some other templating engine (not
+ *      recommended, e.g. in issue [#4006](https://github.com/angular/angular.js/issues/4006)),
+ *      remember to escape your regular expression (and be aware that you might need more than
+ *      one level of escaping depending on your templating engine and the way you interpolated
+ *      the value.)  Do make use of your platform's escaping mechanism as it might be good
+ *      enough before coding your own.  e.g. Ruby has
+ *      [Regexp.escape(str)](http://www.ruby-doc.org/core-2.0.0/Regexp.html#method-c-escape)
+ *      and Python has [re.escape](http://docs.python.org/library/re.html#re.escape).
+ *      Javascript lacks a similar built in function for escaping.  Take a look at Google
+ *      Closure library's [goog.string.regExpEscape(s)](
+ *      http://docs.closure-library.googlecode.com/git/closure_goog_string_string.js.source.html#line962).
+ *
+ * Refer {@link ng.$sceDelegateProvider $sceDelegateProvider} for an example.

+  /* Design notes on the default implementation for SCE.
+   *
+   * The API contract for the SCE delegate
+   * -------------------------------------
+   * The SCE delegate object must provide the following 3 methods:
+   *
+   * - trustAs(contextEnum, value)
+   *     This method is used to tell the SCE service that the provided value is OK to use in the
+   *     contexts specified by contextEnum.  It must return an object that will be accepted by
+   *     getTrusted() for a compatible contextEnum and return this value.
+   *
+   * - valueOf(value)
+   *     For values that were not produced by trustAs(), return them as is.  For values that were
+   *     produced by trustAs(), return the corresponding input value to trustAs.  Basically, if
+   *     trustAs is wrapping the given values into some type, this operation unwraps it when given
+   *     such a value.
+   *
+   * - getTrusted(contextEnum, value)
+   *     This function should return the a value that is safe to use in the context specified by
+   *     contextEnum or throw and exception otherwise.
+   *
+   * NOTE: This contract deliberately does NOT state that values returned by trustAs() must be
+   * opaque or wrapped in some holder object.  That happens to be an implementation detail.  For
+   * instance, an implementation could maintain a registry of all trusted objects by context.  In
+   * such a case, trustAs() would return the same object that was passed in.  getTrusted() would
+   * return the same object passed in if it was found in the registry under a compatible context or
+   * throw an exception otherwise.  An implementation might only wrap values some of the time based
+   * on some criteria.  getTrusted() might return a value and not throw an exception for special
+   * constants or objects even if not wrapped.  All such implementations fulfill this contract.
+   *
+   *
+   * A note on the inheritance model for SCE contexts
+   * ------------------------------------------------
+   * I've used inheritance and made RESOURCE_URL wrapped types a subtype of URL wrapped types.  This
+   * is purely an implementation details.
+   *
+   * The contract is simply this:
+   *
+   *     getTrusted($sce.RESOURCE_URL, value) succeeding implies that getTrusted($sce.URL, value)
+   *     will also succeed.
+   *
+   * Inheritance happens to capture this in a natural way.  In some future, we
+   * may not use inheritance anymore.  That is OK because no code outside of
+   * sce.js and sceSpecs.js would need to be aware of this detail.

+ *
+ * Implementation Notes for non-IE browsers
+ * ----------------------------------------
+ * Assigning a URL to the href property of an anchor DOM node, even one attached to the DOM,
+ * results both in the normalizing and parsing of the URL.  Normalizing means that a relative
+ * URL will be resolved into an absolute URL in the context of the application document.
+ * Parsing means that the anchor node's host, hostname, protocol, port, pathname and related
+ * properties are all populated to reflect the normalized URL.  This approach has wide
+ * compatibility - Safari 1+, Mozilla 1+, Opera 7+,e etc.  See
+ * http://www.aptana.com/reference/html/api/HTMLAnchorElement.html
+ *
+ * Implementation Notes for IE
+ * ---------------------------
+ * IE >= 8 and <= 10 normalizes the URL when assigned to the anchor node similar to the other
+ * browsers.  However, the parsed components will not be set if the URL assigned did not specify
+ * them.  (e.g. if you assign a.href = "foo", then a.protocol, a.host, etc. will be empty.)  We
+ * work around that by performing the parsing in a 2nd step by taking a previously normalized
+ * URL (e.g. by assigning to a.href) and assigning it a.href again.  This correctly populates the
+ * properties such as protocol, hostname, port, etc.
+ *
+ * IE7 does not normalize the URL when assigned to an anchor node.  (Apparently, it does, if one
+ * uses the inner HTML approach to assign the URL as part of an HTML snippet -
+ * http://stackoverflow.com/a/472729)  However, setting img[src] does normalize the URL.
+ * Unfortunately, setting img[src] to something like "javascript:foo" on IE throws an exception.
+ * Since the primary usage for normalizing URLs is to sanitize such URLs, we can't use that
+ * method and IE < 8 is unsupported.
+ *

+ * @ngdoc filter
+ * @name ng.filter:filter
+ * @function
+ *
+ * @description
+ * Selects a subset of items from `array` and returns it as a new array.
+ *
+ * @param {Array} array The source array.
+ * @param {string|Object|function()} expression The predicate to be used for selecting items from
+ *   `array`.
+ *
+ *   Can be one of:
+ *
+ *   - `string`: The string is evaluated as an expression and the resulting value is used for substring match against
+ *     the contents of the `array`. All strings or objects with string properties in `array` that contain this string
+ *     will be returned. The predicate can be negated by prefixing the string with `!`.
+ *
+ *   - `Object`: A pattern object can be used to filter specific properties on objects contained
+ *     by `array`. For example `{name:"M", phone:"1"}` predicate will return an array of items
+ *     which have property `name` containing "M" and property `phone` containing "1". A special
+ *     property name `$` can be used (as in `{$:"text"}`) to accept a match against any
+ *     property of the object. That's equivalent to the simple substring match with a `string`
+ *     as described above.
+ *
+ *   - `function(value)`: A predicate function can be used to write arbitrary filters. The function is
+ *     called for each element of `array`. The final result is an array of those elements that
+ *     the predicate returned true for.
+ *
+ * @param {function(actual, expected)|true|undefined} comparator Comparator which is used in
+ *     determining if the expected value (from the filter expression) and actual value (from
+ *     the object in the array) should be considered a match.
+ *
+ *   Can be one of:
+ *
+ *     - `function(actual, expected)`:
+ *       The function will be given the object value and the predicate value to compare and
+ *       should return true if the item should be included in filtered result.
+ *
+ *     - `true`: A shorthand for `function(actual, expected) { return angular.equals(expected, actual)}`.
+ *       this is essentially strict comparison of expected and actual.
+ *
+ *     - `false|undefined`: A short hand for a function which will look for a substring match in case
+ *       insensitive way.

+ * @ngdoc filter
+ * @name ng.filter:date
+ * @function
+ *
+ * @description
+ *   Formats `date` to a string based on the requested `format`.
+ *
+ *   `format` string can be composed of the following elements:
+ *
+ *   * `'yyyy'`: 4 digit representation of year (e.g. AD 1 => 0001, AD 2010 => 2010)
+ *   * `'yy'`: 2 digit representation of year, padded (00-99). (e.g. AD 2001 => 01, AD 2010 => 10)
+ *   * `'y'`: 1 digit representation of year, e.g. (AD 1 => 1, AD 199 => 199)
+ *   * `'MMMM'`: Month in year (January-December)
+ *   * `'MMM'`: Month in year (Jan-Dec)
+ *   * `'MM'`: Month in year, padded (01-12)
+ *   * `'M'`: Month in year (1-12)
+ *   * `'dd'`: Day in month, padded (01-31)
+ *   * `'d'`: Day in month (1-31)
+ *   * `'EEEE'`: Day in Week,(Sunday-Saturday)
+ *   * `'EEE'`: Day in Week, (Sun-Sat)
+ *   * `'HH'`: Hour in day, padded (00-23)
+ *   * `'H'`: Hour in day (0-23)
+ *   * `'hh'`: Hour in am/pm, padded (01-12)
+ *   * `'h'`: Hour in am/pm, (1-12)
+ *   * `'mm'`: Minute in hour, padded (00-59)
+ *   * `'m'`: Minute in hour (0-59)
+ *   * `'ss'`: Second in minute, padded (00-59)
+ *   * `'s'`: Second in minute (0-59)
+ *   * `'.sss' or ',sss'`: Millisecond in second, padded (000-999)
+ *   * `'a'`: am/pm marker
+ *   * `'Z'`: 4 digit (+sign) representation of the timezone offset (-1200-+1200)
+ *
+ *   `format` string can also be one of the following predefined
+ *   {@link guide/i18n localizable formats}:
+ *
+ *   * `'medium'`: equivalent to `'MMM d, y h:mm:ss a'` for en_US locale
+ *     (e.g. Sep 3, 2010 12:05:08 pm)
+ *   * `'short'`: equivalent to `'M/d/yy h:mm a'` for en_US  locale (e.g. 9/3/10 12:05 pm)
+ *   * `'fullDate'`: equivalent to `'EEEE, MMMM d,y'` for en_US  locale
+ *     (e.g. Friday, September 3, 2010)
+ *   * `'longDate'`: equivalent to `'MMMM d, y'` for en_US  locale (e.g. September 3, 2010)
+ *   * `'mediumDate'`: equivalent to `'MMM d, y'` for en_US  locale (e.g. Sep 3, 2010)
+ *   * `'shortDate'`: equivalent to `'M/d/yy'` for en_US locale (e.g. 9/3/10)
+ *   * `'mediumTime'`: equivalent to `'h:mm:ss a'` for en_US locale (e.g. 12:05:08 pm)
+ *   * `'shortTime'`: equivalent to `'h:mm a'` for en_US locale (e.g. 12:05 pm)
+ *
+ *   `format` string can contain literal values. These need to be quoted with single quotes (e.g.
+ *   `"h 'in the morning'"`). In order to output single quote, use two single quotes in a sequence
+ *   (e.g. `"h 'o''clock'"`).
+ *
+ * @param {(Date|number|string)} date Date to format either as Date object, milliseconds (string or
+ *    number) or various ISO 8601 datetime string formats (e.g. yyyy-MM-ddTHH:mm:ss.SSSZ and its
+ *    shorter versions like yyyy-MM-ddTHH:mmZ, yyyy-MM-dd or yyyyMMddTHHmmssZ). If no timezone is
+ *    specified in the string input, the time is considered to be in the local timezone.
+ * @param {string=} format Formatting rules (see Description). If not specified,
+ *    `mediumDate` is used.
+ * @returns {string} Formatted string or the input if input is not recognized as date/millis.

+ *    - `string`: An Angular expression which evaluates to an object to order by, such as 'name'
+ *      to sort by a property called 'name'. Optionally prefixed with `+` or `-` to control
+ *      ascending or descending sort order (for example, +name or -name).
+ *    - `Array`: An array of function or string predicates. The first predicate in the array
+ *      is used for sorting, but when two items are equivalent, the next predicate is used.
+ *
+ * @param {boolean=} reverse Reverse the order the array.
+ * @returns {Array} Sorted copy of the source array.

+ * Directive that instantiates
+ * {@link ng.directive:form.FormController FormController}.
+ *
+ * If the `name` attribute is specified, the form controller is published onto the current scope under
+ * this name.
+ *
+ * # Alias: {@link ng.directive:ngForm `ngForm`}
+ *
+ * In Angular forms can be nested. This means that the outer form is valid when all of the child
+ * forms are valid as well. However, browsers do not allow nesting of `<form>` elements, so
+ * Angular provides the {@link ng.directive:ngForm `ngForm`} directive which behaves identically to
+ * `<form>` but can be nested.  This allows you to have nested forms, which is very useful when
+ * using Angular validation directives in forms that are dynamically generated using the
+ * {@link ng.directive:ngRepeat `ngRepeat`} directive. Since you cannot dynamically generate the `name`
+ * attribute of input elements using interpolation, you have to wrap each set of repeated inputs in an
+ * `ngForm` directive and nest these in an outer `form` element.
+ *
+ *
+ * # CSS classes
+ *  - `ng-valid` is set if the form is valid.
+ *  - `ng-invalid` is set if the form is invalid.
+ *  - `ng-pristine` is set if the form is pristine.
+ *  - `ng-dirty` is set if the form is dirty.
+ *
+ *
+ * # Submitting a form and preventing the default action
+ *
+ * Since the role of forms in client-side Angular applications is different than in classical
+ * roundtrip apps, it is desirable for the browser not to translate the form submission into a full
+ * page reload that sends the data to the server. Instead some javascript logic should be triggered
+ * to handle the form submission in an application-specific way.
+ *
+ * For this reason, Angular prevents the default action (form submission to the server) unless the
+ * `<form>` element has an `action` attribute specified.
+ *
+ * You can use one of the following two ways to specify what javascript method should be called when
+ * a form is submitted:
+ *
+ * - {@link ng.directive:ngSubmit ngSubmit} directive on the form element
+ * - {@link ng.directive:ngClick ngClick} directive on the first
+  *  button or input field of type submit (input[type=submit])
+ *
+ * To prevent double execution of the handler, use only one of the {@link ng.directive:ngSubmit ngSubmit}
+ * or {@link ng.directive:ngClick ngClick} directives.
+ * This is because of the following form submission rules in the HTML specification:
+ *
+ * - If a form has only one input field then hitting enter in this field triggers form submit
+ * (`ngSubmit`)
+ * - if a form has 2+ input fields and no buttons or input[type=submit] then hitting enter
+ * doesn't trigger submit
+ * - if a form has one or more input fields and one or more buttons or input[type=submit] then
+ * hitting enter in any of the input fields will trigger the click handler on the *first* button or
+ * input[type=submit] (`ngClick`) *and* a submit handler on the enclosing form (`ngSubmit`)
+ *
+ * @param {string=} name Name of the form. If specified, the form controller will be published into
+ *                       related scope, under this name.

+ * `NgModelController` provides API for the `ng-model` directive. The controller contains
+ * services for data-binding, validation, CSS updates, and value formatting and parsing. It
+ * purposefully does not contain any logic which deals with DOM rendering or listening to
+ * DOM events. Such DOM related logic should be provided by other directives which make use of
+ * `NgModelController` for data-binding.
+ *
+ * ## Custom Control Example
+ * This example shows how to use `NgModelController` with a custom control to achieve
+ * data-binding. Notice how different directives (`contenteditable`, `ng-model`, and `required`)
+ * collaborate together to achieve the desired result.
+ *
+ * Note that `contenteditable` is an HTML5 attribute, which tells the browser to let the element
+ * contents be edited in place by the user.  This will not work on older browsers.
+ *
+ * <example module="customControl">
+    <file name="style.css">
+      [contenteditable] {
+        border: 1px solid black;
+        background-color: white;

+ * @description
+ * The `ngModel` directive binds an `input`,`select`, `textarea` (or custom form control) to a
+ * property on the scope using {@link ng.directive:ngModel.NgModelController NgModelController},
+ * which is created and exposed by this directive.
+ *
+ * `ngModel` is responsible for:
+ *
+ * - Binding the view into the model, which other directives such as `input`, `textarea` or `select`
+ *   require.
+ * - Providing validation behavior (i.e. required, number, email, url).
+ * - Keeping the state of the control (valid/invalid, dirty/pristine, validation errors).
+ * - Setting related css classes on the element (`ng-valid`, `ng-invalid`, `ng-dirty`, `ng-pristine`).
+ * - Registering the control with its parent {@link ng.directive:form form}.
+ *
+ * Note: `ngModel` will try to bind to the property given by evaluating the expression on the
+ * current scope. If the property doesn't already exist on this scope, it will be created
+ * implicitly and added to the scope.
+ *
+ * For best practices on using `ngModel`, see:

+
+   The example below demonstrates how to perform animations using ngClass.

+         transition:all cubic-bezier(0.250, 0.460, 0.450, 0.940) 0.5s;
+       }
+
+       .base-class.my-class {
+         color: red;
+         font-size:3em;

+       it('should check ng-class', function() {
+         expect(element(by.css('.base-class')).getAttribute('class')).not.
+           toMatch(/my-class/);
+
+         element(by.id('setbtn')).click();
+

+       });
+     </file>
+   </example>
+
+
+   ## ngClass and pre-existing CSS3 Transitions/Animations
+   The ngClass directive still supports CSS3 Transitions/Animations even if they do not follow the ngAnimate CSS naming structure.
+   Upon animation ngAnimate will apply supplementary CSS classes to track the start and end of an animation, but this will not hinder
+   any pre-existing CSS transitions already on the element. To get an idea of what happens during a class-based animation, be sure
+   to view the step by step details of {@link ngAnimate.$animate#methods_addclass $animate.addClass} and
+   {@link ngAnimate.$animate#methods_removeclass $animate.removeClass}.

+ * @ngdoc directive
+ * @name ng.directive:ngCloak
+ * @restrict AC
+ *
+ * @description
+ * The `ngCloak` directive is used to prevent the Angular html template from being briefly
+ * displayed by the browser in its raw (uncompiled) form while your application is loading. Use this
+ * directive to avoid the undesirable flicker effect caused by the html template display.
+ *
+ * The directive can be applied to the `<body>` element, but the preferred usage is to apply
+ * multiple `ngCloak` directives to small portions of the page to permit progressive rendering
+ * of the browser view.
+ *
+ * `ngCloak` works in cooperation with the following css rule embedded within `angular.js` and
+ * `angular.min.js`.
+ * For CSP mode please add `angular-csp.css` to your html file (see {@link ng.directive:ngCsp ngCsp}).
+ *
+ * <pre>
+ * [ng\:cloak], [ng-cloak], [data-ng-cloak], [x-ng-cloak], .ng-cloak, .x-ng-cloak {
+ *   display: none !important;
+ * }
+ * </pre>
+ *
+ * When this css rule is loaded by the browser, all html elements (including their children) that
+ * are tagged with the `ngCloak` directive are hidden. When Angular encounters this directive
+ * during the compilation of the template it deletes the `ngCloak` element attribute, making
+ * the compiled element visible.
+ *
+ * For the best result, the `angular.js` script must be loaded in the head section of the html
+ * document; alternatively, the css rule above must be included in the external stylesheet of the
+ * application.
+ *
+ * Legacy browsers, like IE7, do not provide attribute selector support (added in CSS 2.1) so they
+ * cannot match the `[ng\:cloak]` selector. To work around this limitation, you must add the css
+ * class `ng-cloak` in addition to the `ngCloak` directive as shown in the example below.
+ *
+ * @element ANY
+ *
+ * @example
+   <doc:example>
+     <doc:source>

+/**
+ * @ngdoc directive
+ * @name ng.directive:ngController
+ *
+ * @description
+ * The `ngController` directive attaches a controller class to the view. This is a key aspect of how angular
+ * supports the principles behind the Model-View-Controller design pattern.
+ *
+ * MVC components in angular:
+ *
+ * * Model — The Model is scope properties; scopes are attached to the DOM where scope properties
+ *   are accessed through bindings.
+ * * View — The template (HTML with data bindings) that is rendered into the View.
+ * * Controller — The `ngController` directive specifies a Controller class; the class contains business
+ *   logic behind the application to decorate the scope with functions and values
+ *
+ * Note that you can also attach controllers to the DOM by declaring it in a route definition
+ * via the {@link ngRoute.$route $route} service. A common mistake is to declare the controller
+ * again using `ng-controller` in the template itself.  This will cause the controller to be attached
+ * and executed twice.
+ *
+ * @element ANY
+ * @scope
+ * @param {expression} ngController Name of a globally accessible constructor function or an
+ *     {@link guide/expression expression} that on the current scope evaluates to a
+ *     constructor function. The controller instance can be published into a scope property
+ *     by specifying `as propertyName`.
+ *
+ * @example
+ * Here is a simple form for editing user contact information. Adding, removing, clearing, and
+ * greeting are methods declared on the controller (see source tab). These methods can
+ * easily be called from the angular markup. Notice that the scope becomes the `this` for the
+ * controller's instance. This allows for easy access to the view data from the controller. Also
+ * notice that any changes to the data are automatically reflected in the View without the need
+ * for a manual update. The example is shown in two different declaration styles you may use
+ * according to preference.

+ * Enables [CSP (Content Security Policy)](https://developer.mozilla.org/en/Security/CSP) support.
+ *
+ * This is necessary when developing things like Google Chrome Extensions.
+ *
+ * CSP forbids apps to use `eval` or `Function(string)` generated functions (among other things).
+ * For us to be compatible, we just need to implement the "getterFn" in $parse without violating
+ * any of these restrictions.
+ *
+ * AngularJS uses `Function(string)` generated functions as a speed optimization. Applying the `ngCsp`
+ * directive will cause Angular to use CSP compatibility mode. When this mode is on AngularJS will
+ * evaluate all expressions up to 30% slower than in non-CSP mode, but no security violations will
+ * be raised.
+ *
+ * CSP forbids JavaScript to inline stylesheet rules. In non CSP mode Angular automatically
+ * includes some CSS rules (e.g. {@link ng.directive:ngCloak ngCloak}).
+ * To make those directives work in CSP mode, include the `angular-csp.css` manually.
+ *
+ * In order to use this feature put the `ngCsp` directive on the root element of the application.
+ *
+ * *Note: This directive is only available in the `ng-csp` and `data-ng-csp` attribute form.*
+ *
+ * @example
+ * This example shows how to apply the `ngCsp` directive to the `html` tag.

+// ngCsp is not implemented as a proper directive any more, because we need it be processed while we bootstrap

+ * @ngdoc directive
+ * @name ng.directive:ngIf
+ * @restrict A
+ *
+ * @description
+ * The `ngIf` directive removes or recreates a portion of the DOM tree based on an
+ * {expression}. If the expression assigned to `ngIf` evaluates to a false
+ * value then the element is removed from the DOM, otherwise a clone of the
+ * element is reinserted into the DOM.
+ *
+ * `ngIf` differs from `ngShow` and `ngHide` in that `ngIf` completely removes and recreates the
+ * element in the DOM rather than changing its visibility via the `display` css property.  A common
+ * case when this difference is significant is when using css selectors that rely on an element's
+ * position within the DOM, such as the `:first-child` or `:last-child` pseudo-classes.
+ *
+ * Note that when an element is removed using `ngIf` its scope is destroyed and a new scope
+ * is created when the element is restored.  The scope created within `ngIf` inherits from
+ * its parent scope using
+ * {@link https://github.com/angular/angular.js/wiki/The-Nuances-of-Scope-Prototypal-Inheritance prototypal inheritance}.
+ * An important implication of this is if `ngModel` is used within `ngIf` to bind to
+ * a javascript primitive defined in the parent scope. In this case any modifications made to the
+ * variable within the child scope will override (hide) the value in the parent scope.
+ *
+ * Also, `ngIf` recreates elements using their compiled state. An example of this behavior
+ * is if an element's class attribute is directly modified after it's compiled, using something like
+ * jQuery's `.addClass()` method, and the element is later removed. When `ngIf` recreates the element
+ * the added class will be lost because the original compiled state is used to regenerate the element.
+ *
+ * Additionally, you can provide animations via the `ngAnimate` module to animate the `enter`
+ * and `leave` effects.
+ *
+ * @animations
+ * enter - happens just after the ngIf contents change and a new DOM element is created and injected into the ngIf container
+ * leave - happens just before the ngIf contents are removed from the DOM
+ *
+ * @element ANY
+ * @scope
+ * @priority 600
+ * @param {expression} ngIf If the {@link guide/expression expression} is falsy then

+/**
+ * @ngdoc directive
+ * @name ng.directive:ngPluralize
+ * @restrict EA
+ *
+ * @description
+ * # Overview
+ * `ngPluralize` is a directive that displays messages according to en-US localization rules.
+ * These rules are bundled with angular.js, but can be overridden
+ * (see {@link guide/i18n Angular i18n} dev guide). You configure ngPluralize directive
+ * by specifying the mappings between
+ * {@link http://unicode.org/repos/cldr-tmp/trunk/diff/supplemental/language_plural_rules.html
+ * plural categories} and the strings to be displayed.
+ *
+ * # Plural categories and explicit number rules
+ * There are two
+ * {@link http://unicode.org/repos/cldr-tmp/trunk/diff/supplemental/language_plural_rules.html
+ * plural categories} in Angular's default en-US locale: "one" and "other".
+ *
+ * While a plural category may match many numbers (for example, in en-US locale, "other" can match
+ * any number that is not 1), an explicit number rule can only match one number. For example, the
+ * explicit number rule for "3" matches the number 3. There are examples of plural categories
+ * and explicit number rules throughout the rest of this documentation.
+ *
+ * # Configuring ngPluralize
+ * You configure ngPluralize by providing 2 attributes: `count` and `when`.
+ * You can also provide an optional attribute, `offset`.
+ *
+ * The value of the `count` attribute can be either a string or an {@link guide/expression
+ * Angular expression}; these are evaluated on the current scope for its bound value.
+ *
+ * The `when` attribute specifies the mappings between plural categories and the actual
+ * string to be displayed. The value of the attribute should be a JSON object.
+ *
+ * The following example shows how to configure ngPluralize:
+ *
+ * <pre>
+ * <ng-pluralize count="personCount"
+                 when="{'0': 'Nobody is viewing.',
+ *                      'one': '1 person is viewing.',
+ *                      'other': '{} people are viewing.'}">
+ * </ng-pluralize>
+ *</pre>
+ *
+ * In the example, `"0: Nobody is viewing."` is an explicit number rule. If you did not
+ * specify this rule, 0 would be matched to the "other" category and "0 people are viewing"
+ * would be shown instead of "Nobody is viewing". You can specify an explicit number rule for
+ * other numbers, for example 12, so that instead of showing "12 people are viewing", you can
+ * show "a dozen people are viewing".
+ *
+ * You can use a set of closed braces (`{}`) as a placeholder for the number that you want substituted
+ * into pluralized strings. In the previous example, Angular will replace `{}` with
+ * <span ng-non-bindable>`{{personCount}}`</span>. The closed braces `{}` is a placeholder
+ * for <span ng-non-bindable>{{numberExpression}}</span>.
+ *
+ * # Configuring ngPluralize with offset
+ * The `offset` attribute allows further customization of pluralized text, which can result in
+ * a better user experience. For example, instead of the message "4 people are viewing this document",
+ * you might display "John, Kate and 2 others are viewing this document".
+ * The offset attribute allows you to offset a number by any desired value.
+ * Let's take a look at an example:
+ *
+ * <pre>
+ * <ng-pluralize count="personCount" offset=2
+ *               when="{'0': 'Nobody is viewing.',
+ *                      '1': '{{person1}} is viewing.',
+ *                      '2': '{{person1}} and {{person2}} are viewing.',
+ *                      'one': '{{person1}}, {{person2}} and one other person are viewing.',
+ *                      'other': '{{person1}}, {{person2}} and {} other people are viewing.'}">
+ * </ng-pluralize>
+ * </pre>
+ *
+ * Notice that we are still using two plural categories(one, other), but we added
+ * three explicit number rules 0, 1 and 2.
+ * When one person, perhaps John, views the document, "John is viewing" will be shown.
+ * When three people view the document, no explicit number rule is found, so
+ * an offset of 2 is taken off 3, and Angular uses 1 to decide the plural category.
+ * In this case, plural category 'one' is matched and "John, Marry and one other person are viewing"
+ * is shown.
+ *
+ * Note that when you specify offsets, you must provide explicit number rules for
+ * numbers from 0 up to and including the offset. If you use an offset of 3, for example,
+ * you must provide explicit number rules for 0, 1, 2 and 3. You must also provide plural strings for
+ * plural categories "one" and "other".
+ *
+ * @param {string|expression} count The variable to be bounded to.
+ * @param {string} when The mapping between plural category to its corresponding strings.
+ * @param {number=} offset Offset to deduct from the total number.
+ *
+ * @example
+    <doc:example>
+      <doc:source>
+        <script>
+          function Ctrl($scope) {
+            $scope.person1 = 'Igor';
+            $scope.person2 = 'Misko';
+            $scope.personCount = 1;
+          }
+        </script>
+        <div ng-controller="Ctrl">
+          Person 1:<input type="text" ng-model="person1" value="Igor" /><br/>

+          Number of People:<input type="text" ng-model="personCount" value="1" /><br/>

+ * | Variable  | Type            | Details                                                                     |
+ * |-----------|-----------------|-----------------------------------------------------------------------------|
+ * | `$index`  | {@type number}  | iterator offset of the repeated element (0..length-1)                       |
+ * | `$first`  | {@type boolean} | true if the repeated element is first in the iterator.                      |
+ * | `$middle` | {@type boolean} | true if the repeated element is between the first and last in the iterator. |
+ * | `$last`   | {@type boolean} | true if the repeated element is last in the iterator.                       |
+ * | `$even`   | {@type boolean} | true if the iterator position `$index` is even (otherwise false).           |
+ * | `$odd`    | {@type boolean} | true if the iterator position `$index` is odd (otherwise false).            |
+ *
+ * Creating aliases for these properties is possible with {@link api/ng.directive:ngInit `ngInit`}.
+ * This may be useful when, for instance, nesting ngRepeats.
+ *
+ * # Special repeat start and end points
+ * To repeat a series of elements instead of just one parent element, ngRepeat (as well as other ng directives) supports extending
+ * the range of the repeater by defining explicit start and end points by using **ng-repeat-start** and **ng-repeat-end** respectively.
+ * The **ng-repeat-start** directive works the same as **ng-repeat**, but will repeat all the HTML code (including the tag it's defined on)
+ * up to and including the ending HTML tag where **ng-repeat-end** is placed.
+ *
+ * The example below makes use of this feature:
+ * <pre>
+ *   <header ng-repeat-start="item in items">
+ *     Header {{ item }}
+ *   </header>
+ *   <div class="body">
+ *     Body {{ item }}
+ *   </div>
+ *   <footer ng-repeat-end>
+ *     Footer {{ item }}
+ *   </footer>
+ * </pre>
+ *
+ * And with an input of {@type ['A','B']} for the items variable in the example above, the output will evaluate to:
+ * <pre>
+ *   <header>
+ *     Header A
+ *   </header>
+ *   <div class="body">
+ *     Body A
+ *   </div>
+ *   <footer>
+ *     Footer A
+ *   </footer>
+ *   <header>
+ *     Header B
+ *   </header>
+ *   <div class="body">
+ *     Body B
+ *   </div>
+ *   <footer>
+ *     Footer B
+ *   </footer>
+ * </pre>
+ *
+ * The custom start and end points for ngRepeat also support all other HTML directive syntax flavors provided in AngularJS (such
+ * as **data-ng-repeat-start**, **x-ng-repeat-start** and **ng:repeat-start**).
+ *
+ * @animations
+ * enter - when a new item is added to the list or when an item is revealed after a filter
+ * leave - when an item is removed from the list or when an item is filtered out
+ * move - when an adjacent item is filtered out causing a reorder or when the item contents are reordered
+ *
+ * @element ANY
+ * @scope
+ * @priority 1000
+ * @param {repeat_expression} ngRepeat The expression indicating how to enumerate a collection. These
+ *   formats are currently supported:
+ *
+ *   * `variable in expression` – where variable is the user defined loop variable and `expression`
+ *     is a scope expression giving the collection to enumerate.
+ *
+ *     For example: `album in artist.albums`.
+ *
+ *   * `(key, value) in expression` – where `key` and `value` can be any user defined identifiers,
+ *     and `expression` is the scope expression giving the collection to enumerate.
+ *
+ *     For example: `(name, age) in {'adam':10, 'amalie':12}`.
+ *
+ *   * `variable in expression track by tracking_expression` – You can also provide an optional tracking function
+ *     which can be used to associate the objects in the collection with the DOM elements. If no tracking function
+ *     is specified the ng-repeat associates elements by identity in the collection. It is an error to have
+ *     more than one tracking function to resolve to the same key. (This would mean that two distinct objects are
+ *     mapped to the same DOM element, which is not possible.)  Filters should be applied to the expression,
+ *     before specifying a tracking expression.
+ *
+ *     For example: `item in items` is equivalent to `item in items track by $id(item)'. This implies that the DOM elements
+ *     will be associated by item identity in the array.
+ *
+ *     For example: `item in items track by $id(item)`. A built in `$id()` function can be used to assign a unique
+ *     `$$hashKey` property to each item in the array. This property is then used as a key to associated DOM elements
+ *     with the corresponding item in the array by identity. Moving the same object in array would move the DOM
+ *     element in the same way in the DOM.
+ *
+ *     For example: `item in items track by item.id` is a typical pattern when the items come from the database. In this
+ *     case the object identity does not matter. Two objects are considered equivalent as long as their `id`
+ *     property is same.
+ *
+ *     For example: `item in items | filter:searchText track by item.id` is a pattern that might be used to apply a filter
+ *     to items in conjunction with a tracking expression.
+ *
+ * @example
+ * This example initializes the scope to a list of names and
+ * then uses `ngRepeat` to display every person:

+/**
+ * @ngdoc directive
+ * @name ng.directive:ngShow
+ *
+ * @description
+ * The `ngShow` directive shows or hides the given HTML element based on the expression
+ * provided to the ngShow attribute. The element is shown or hidden by removing or adding
+ * the `ng-hide` CSS class onto the element. The `.ng-hide` CSS class is predefined
+ * in AngularJS and sets the display style to none (using an !important flag).
+ * For CSP mode please add `angular-csp.css` to your html file (see {@link ng.directive:ngCsp ngCsp}).
+ *
+ * <pre>
+ * <!-- when $scope.myValue is truthy (element is visible) -->
+ * <div ng-show="myValue"></div>
+ *
+ * <!-- when $scope.myValue is falsy (element is hidden) -->
+ * <div ng-show="myValue" class="ng-hide"></div>
+ * </pre>
+ *
+ * When the ngShow expression evaluates to false then the ng-hide CSS class is added to the class attribute
+ * on the element causing it to become hidden. When true, the ng-hide CSS class is removed
+ * from the element causing the element not to appear hidden.
+ *
+ * ## Why is !important used?
+ *
+ * You may be wondering why !important is used for the .ng-hide CSS class. This is because the `.ng-hide` selector
+ * can be easily overridden by heavier selectors. For example, something as simple
+ * as changing the display style on a HTML list item would make hidden elements appear visible.
+ * This also becomes a bigger issue when dealing with CSS frameworks.
+ *
+ * By using !important, the show and hide behavior will work as expected despite any clash between CSS selector
+ * specificity (when !important isn't used with any conflicting styles). If a developer chooses to override the
+ * styling to change how to hide an element then it is just a matter of using !important in their own CSS code.
+ *
+ * ### Overriding .ng-hide
+ *
+ * If you wish to change the hide behavior with ngShow/ngHide then this can be achieved by
+ * restating the styles for the .ng-hide class in CSS:
+ * <pre>
+ * .ng-hide {
+ *   //!annotate CSS Specificity|Not to worry, this will override the AngularJS default...
+ *   display:block!important;

+/**
+ * @ngdoc directive
+ * @name ng.directive:ngHide
+ *
+ * @description
+ * The `ngHide` directive shows or hides the given HTML element based on the expression
+ * provided to the ngHide attribute. The element is shown or hidden by removing or adding
+ * the `ng-hide` CSS class onto the element. The `.ng-hide` CSS class is predefined
+ * in AngularJS and sets the display style to none (using an !important flag).
+ * For CSP mode please add `angular-csp.css` to your html file (see {@link ng.directive:ngCsp ngCsp}).
+ *
+ * <pre>
+ * <!-- when $scope.myValue is truthy (element is hidden) -->
+ * <div ng-hide="myValue"></div>
+ *
+ * <!-- when $scope.myValue is falsy (element is visible) -->
+ * <div ng-hide="myValue" class="ng-hide"></div>
+ * </pre>
+ *
+ * When the ngHide expression evaluates to true then the .ng-hide CSS class is added to the class attribute
+ * on the element causing it to become hidden. When false, the ng-hide CSS class is removed
+ * from the element causing the element not to appear hidden.
+ *
+ * ## Why is !important used?
+ *
+ * You may be wondering why !important is used for the .ng-hide CSS class. This is because the `.ng-hide` selector
+ * can be easily overridden by heavier selectors. For example, something as simple
+ * as changing the display style on a HTML list item would make hidden elements appear visible.
+ * This also becomes a bigger issue when dealing with CSS frameworks.
+ *
+ * By using !important, the show and hide behavior will work as expected despite any clash between CSS selector
+ * specificity (when !important isn't used with any conflicting styles). If a developer chooses to override the
+ * styling to change how to hide an element then it is just a matter of using !important in their own CSS code.
+ *
+ * ### Overriding .ng-hide
+ *
+ * If you wish to change the hide behavior with ngShow/ngHide then this can be achieved by
+ * restating the styles for the .ng-hide class in CSS:
+ * <pre>
+ * .ng-hide {
+ *   //!annotate CSS Specificity|Not to worry, this will override the AngularJS default...
+ *   display:block!important;
+ *
+ *   //this is just another form of hiding an element
+ *   position:absolute;
+ *   top:-9999px;
+ *   left:-9999px;
+ * }
+ * </pre>
+ *
+ * Just remember to include the important flag so the CSS override will function.
+ * 
+ * <div class="alert alert-warning">
+ * **Note:** Here is a list of values that ngHide will consider as a falsy value (case insensitive):<br />
+ * "f" / "0" / "false" / "no" / "n" / "[]"
+ * </div>

+ * @ngdoc directive

+ * @restrict EA
+ *
+ * @description
+ * The `ngSwitch` directive is used to conditionally swap DOM structure on your template based on a scope expression.
+ * Elements within `ngSwitch` but without `ngSwitchWhen` or `ngSwitchDefault` directives will be preserved at the location
+ * as specified in the template.
+ *
+ * The directive itself works similar to ngInclude, however, instead of downloading template code (or loading it
+ * from the template cache), `ngSwitch` simply chooses one of the nested elements and makes it visible based on which element
+ * matches the value obtained from the evaluated expression. In other words, you define a container element
+ * (where you place the directive), place an expression on the **`on="..."` attribute**
+ * (or the **`ng-switch="..."` attribute**), define any inner elements inside of the directive and place
+ * a when attribute per element. The when attribute is used to inform ngSwitch which element to display when the on
+ * expression is evaluated. If a matching expression is not found via a when attribute then an element with the default
+ * attribute is displayed.
+ *
+ * <div class="alert alert-info">
+ * Be aware that the attribute values to match against cannot be expressions. They are interpreted
+ * as literal string values to match against.
+ * For example, **`ng-switch-when="someVal"`** will match against the string `"someVal"` not against the
+ * value of the expression `$scope.someVal`.
+ * </div>
+
+ * @animations
+ * enter - happens after the ngSwitch contents change and the matched child element is placed inside the container
+ * leave - happens just after the ngSwitch contents change and just before the former contents are removed from the DOM

+ * @param {*} ngSwitch|on expression to match against <tt>ng-switch-when</tt>.
+ * @paramDescription
+ * On child elements add:

+ * * `ngSwitchWhen`: the case statement to match against. If match then this
+ *   case will be displayed. If the same match appears multiple times, all the
+ *   elements will be displayed.
+ * * `ngSwitchDefault`: the default case when no other case match. If there
+ *   are multiple default cases, all of them will be displayed when no other
+ *   case match.

+ * @ngdoc directive

+ * @restrict E
+ *
+ * @description
+ * HTML `SELECT` element with angular data-binding.
+ *
+ * # `ngOptions`
+ *
+ * The `ngOptions` attribute can be used to dynamically generate a list of `<option>`
+ * elements for the `<select>` element using the array or object obtained by evaluating the
+ * `ngOptions` comprehension_expression.
+ *
+ * When an item in the `<select>` menu is selected, the array element or object property
+ * represented by the selected option will be bound to the model identified by the `ngModel`
+ * directive.
+ *
+ * <div class="alert alert-warning">
+ * **Note:** `ngModel` compares by reference, not value. This is important when binding to an
+ * array of objects. See an example {@link http://jsfiddle.net/qWzTb/ in this jsfiddle}.
+ * </div>
+ *
+ * Optionally, a single hard-coded `<option>` element, with the value set to an empty string, can
+ * be nested into the `<select>` element. This element will then represent the `null` or "not selected"
+ * option. See example below for demonstration.
+ *
+ * <div class="alert alert-warning">
+ * **Note:** `ngOptions` provides an iterator facility for the `<option>` element which should be used instead
+ * of {@link ng.directive:ngRepeat ngRepeat} when you want the
+ * `select` model to be bound to a non-string value. This is because an option element can only
+ * be bound to string values at present.
+ * </div>
+ *
+ * @param {string} ngModel Assignable angular expression to data-bind to.
+ * @param {string=} name Property name of the form under which the control is published.
+ * @param {string=} required The control is considered valid only if value is entered.
+ * @param {string=} ngRequired Adds `required` attribute and `required` validation constraint to
+ *    the element when the ngRequired expression evaluates to true. Use `ngRequired` instead of
+ *    `required` when you want to data-bind to the `required` attribute.
+ * @param {comprehension_expression=} ngOptions in one of the following forms:
+ *
+ *   * for array data sources:
+ *     * `label` **`for`** `value` **`in`** `array`
+ *     * `select` **`as`** `label` **`for`** `value` **`in`** `array`
+ *     * `label`  **`group by`** `group` **`for`** `value` **`in`** `array`
+ *     * `select` **`as`** `label` **`group by`** `group` **`for`** `value` **`in`** `array` **`track by`** `trackexpr`
+ *   * for object data sources:
+ *     * `label` **`for (`**`key` **`,`** `value`**`) in`** `object`
+ *     * `select` **`as`** `label` **`for (`**`key` **`,`** `value`**`) in`** `object`
+ *     * `label` **`group by`** `group` **`for (`**`key`**`,`** `value`**`) in`** `object`
+ *     * `select` **`as`** `label` **`group by`** `group`
+ *         **`for` `(`**`key`**`,`** `value`**`) in`** `object`
+ *
+ * Where:
+ *
+ *   * `array` / `object`: an expression which evaluates to an array / object to iterate over.
+ *   * `value`: local variable which will refer to each item in the `array` or each property value
+ *      of `object` during iteration.
+ *   * `key`: local variable which will refer to a property name in `object` during iteration.
+ *   * `label`: The result of this expression will be the label for `<option>` element. The
+ *     `expression` will most likely refer to the `value` variable (e.g. `value.propertyName`).
+ *   * `select`: The result of this expression will be bound to the model of the parent `<select>`
+ *      element. If not specified, `select` expression will default to `value`.
+ *   * `group`: The result of this expression will be used to group options using the `<optgroup>`
+ *      DOM element.
+ *   * `trackexpr`: Used when working with an array of objects. The result of this expression will be
+ *      used to identify the objects in the array. The `trackexpr` will most likely refer to the
+ *     `value` variable (e.g. `value.propertyName`).

+ * This object provides a utility for producing rich Error messages within
+ * Angular. It can be called as follows:
+ *
+ * var exampleMinErr = minErr('example');
+ * throw exampleMinErr('one', 'This {0} is {1}', foo, bar);
+ *
+ * The above creates an instance of minErr in the example namespace. The
+ * resulting error will have a namespaced error code of example.one.  The
+ * resulting error will replace {0} with the value of foo, and {1} with the
+ * value of bar. The object is not restricted in the number of arguments it can
+ * take.
+ *
+ * If fewer arguments are specified than necessary for interpolation, the extra
+ * interpolation markers will be preserved in the final string.
+ *
+ * Since data will be parsed statically during a build step, some restrictions
+ * are applied with respect to how minErr instances are created and called.
+ * Instances should have names of the form namespaceMinErr for a minErr created
+ * using minErr('namespace') . Error codes, namespaces and template strings
+ * should all be static strings, not variables or general expressions.
+ *
+ * @param {string} module The namespace to use for the new minErr instance.

+/**
+ * @ngdoc function
+ * @name angular.element
+ * @function
+ *
+ * @description
+ * Wraps a raw DOM element or HTML string as a [jQuery](http://jquery.com) element.
+ *
+ * If jQuery is available, `angular.element` is an alias for the
+ * [jQuery](http://api.jquery.com/jQuery/) function. If jQuery is not available, `angular.element`
+ * delegates to Angular's built-in subset of jQuery, called "jQuery lite" or "jqLite."
+ *
+ * <div class="alert alert-success">jqLite is a tiny, API-compatible subset of jQuery that allows
+ * Angular to manipulate the DOM in a cross-browser compatible way. **jqLite** implements only the most
+ * commonly needed functionality with the goal of having a very small footprint.</div>
+ *
+ * To use jQuery, simply load it before `DOMContentLoaded` event fired.
+ *
+ * <div class="alert">**Note:** all element references in Angular are always wrapped with jQuery or
+ * jqLite; they are never raw DOM references.</div>
+ *
+ * ## Angular's jqLite
+ * jqLite provides only the following jQuery methods:
+ *
+ * - [`addClass()`](http://api.jquery.com/addClass/)
+ * - [`after()`](http://api.jquery.com/after/)
+ * - [`append()`](http://api.jquery.com/append/)
+ * - [`attr()`](http://api.jquery.com/attr/)
+ * - [`bind()`](http://api.jquery.com/bind/) - Does not support namespaces, selectors or eventData
+ * - [`children()`](http://api.jquery.com/children/) - Does not support selectors
+ * - [`clone()`](http://api.jquery.com/clone/)
+ * - [`contents()`](http://api.jquery.com/contents/)
+ * - [`css()`](http://api.jquery.com/css/)
+ * - [`data()`](http://api.jquery.com/data/)
+ * - [`empty()`](http://api.jquery.com/empty/)
+ * - [`eq()`](http://api.jquery.com/eq/)
+ * - [`find()`](http://api.jquery.com/find/) - Limited to lookups by tag name
+ * - [`hasClass()`](http://api.jquery.com/hasClass/)
+ * - [`html()`](http://api.jquery.com/html/)
+ * - [`next()`](http://api.jquery.com/next/) - Does not support selectors
+ * - [`on()`](http://api.jquery.com/on/) - Does not support namespaces, selectors or eventData
+ * - [`off()`](http://api.jquery.com/off/) - Does not support namespaces or selectors
+ * - [`one()`](http://api.jquery.com/one/) - Does not support namespaces or selectors
+ * - [`parent()`](http://api.jquery.com/parent/) - Does not support selectors
+ * - [`prepend()`](http://api.jquery.com/prepend/)
+ * - [`prop()`](http://api.jquery.com/prop/)
+ * - [`ready()`](http://api.jquery.com/ready/)
+ * - [`remove()`](http://api.jquery.com/remove/)
+ * - [`removeAttr()`](http://api.jquery.com/removeAttr/)
+ * - [`removeClass()`](http://api.jquery.com/removeClass/)
+ * - [`removeData()`](http://api.jquery.com/removeData/)
+ * - [`replaceWith()`](http://api.jquery.com/replaceWith/)
+ * - [`text()`](http://api.jquery.com/text/)
+ * - [`toggleClass()`](http://api.jquery.com/toggleClass/)
+ * - [`triggerHandler()`](http://api.jquery.com/triggerHandler/) - Passes a dummy event object to handlers.
+ * - [`unbind()`](http://api.jquery.com/unbind/) - Does not support namespaces
+ * - [`val()`](http://api.jquery.com/val/)
+ * - [`wrap()`](http://api.jquery.com/wrap/)
+ *
+ * ## jQuery/jqLite Extras
+ * Angular also provides the following additional methods and events to both jQuery and jqLite:
+ *
+ * ### Events
+ * - `$destroy` - AngularJS intercepts all jqLite/jQuery's DOM destruction apis and fires this event
+ *    on all DOM nodes being removed.  This can be used to clean up any 3rd party bindings to the DOM
+ *    element before it is removed.
+ *
+ * ### Methods
+ * - `controller(name)` - retrieves the controller of the current element or its parent. By default
+ *   retrieves controller associated with the `ngController` directive. If `name` is provided as
+ *   camelCase directive name, then the controller for this directive will be retrieved (e.g.
+ *   `'ngModel'`).
+ * - `injector()` - retrieves the injector of the current element or its parent.
+ * - `scope()` - retrieves the {@link api/ng.$rootScope.Scope scope} of the current
+ *   element or its parent.
+ * - `isolateScope()` - retrieves an isolate {@link api/ng.$rootScope.Scope scope} if one is attached directly to the
+ *   current element. This getter should be used only on elements that contain a directive which starts a new isolate
+ *   scope. Calling `scope()` on this element always returns the original non-isolate scope.
+ * - `inheritedData()` - same as `data()`, but walks up the DOM until a value is found or the top
+ *   parent element is reached.
+ *
+ * @param {string|DOMElement} element HTML string or DOMElement to be wrapped into jQuery.
+ * @returns {Object} jQuery object.

+ * @ngdoc function
+ * @name angular.injector
+ * @function
+ *
+ * @description
+ * Creates an injector function that can be used for retrieving services as well as for
+ * dependency injection (see {@link guide/di dependency injection}).
+ *
+
+ * @param {Array.<string|Function>} modules A list of module functions or their aliases. See
+ *        {@link angular.module}. The `ng` module must be explicitly added.
+ * @returns {function()} Injector function. See {@link AUTO.$injector $injector}.
+ *
+ * @example
+ * Typical usage
+ * <pre>
+ *   // create an injector
+ *   var $injector = angular.injector(['ng']);
+ *
+ *   // use the injector to kick off your application
+ *   // use the type inference to auto inject arguments, or use implicit injection
+ *   $injector.invoke(function($rootScope, $compile, $document){
+ *     $compile($document)($rootScope);
+ *     $rootScope.$digest();
+ *   });
+ * </pre>
+ *
+ * Sometimes you want to get access to the injector of a currently running Angular app
+ * from outside Angular. Perhaps, you want to inject and compile some markup after the
+ * application has been bootstrapped. You can do this using extra `injector()` added
+ * to JQuery/jqLite elements. See {@link angular.element}.
+ *
+ * *This is fairly rare but could be the case if a third party library is injecting the
+ * markup.*
+ *
+ * In the following example a new block of HTML containing a `ng-controller`
+ * directive is added to the end of the document body by JQuery. We then compile and link
+ * it into the current AngularJS scope.
+ *
+ * <pre>
+ * var $div = $('<div ng-controller="MyCtrl">{{content.label}}</div>');
+ * $(document.body).append($div);
+ *

+ * # Injection Function Annotation
+ *
+ * JavaScript does not have annotations, and annotations are needed for dependency injection. The
+ * following are all valid ways of annotating function with injection arguments and are equivalent.
+ *
+ * <pre>
+ *   // inferred (only works if code not minified/obfuscated)
+ *   $injector.invoke(function(serviceA){});
+ *
+ *   // annotated
+ *   function explicit(serviceA) {};

+ *
+ *   // inline
+ *   $injector.invoke(['serviceA', function(serviceA){}]);
+ * </pre>
+ *
+ * ## Inference
+ *
+ * In JavaScript calling `toString()` on a function returns the function definition. The definition
+ * can then be parsed and the function arguments can be extracted. *NOTE:* This does not work with
+ * minification, and obfuscation tools since these tools change the argument names.
+ *
+ * ## `$inject` Annotation
+ * By adding a `$inject` property onto a function the injection parameters can be specified.
+ *
+ * ## Inline

+ * @methodOf AUTO.$injector
+ *
+ * @description
+ * Returns an array of service names which the function is requesting for injection. This API is
+ * used by the injector to determine which services need to be injected into the function when the
+ * function is invoked. There are three ways in which the function can be annotated with the needed
+ * dependencies.
+ *
+ * # Argument names
+ *
+ * The simplest form is to extract the dependencies from the arguments of the function. This is done
+ * by converting the function into a string using `toString()` method and extracting the argument
+ * names.
+ * <pre>
+ *   // Given
+ *   function MyController($scope, $route) {
+ *     // ...
+ *   }
+ *
+ *   // Then
+ *   expect(injector.annotate(MyController)).toEqual(['$scope', '$route']);
+ * </pre>
+ *
+ * This method does not work with code minification / obfuscation. For this reason the following
+ * annotation strategies are supported.
+ *
+ * # The `$inject` property
+ *
+ * If a function has an `$inject` property and its value is an array of strings, then the strings
+ * represent names of services to be injected into the function.
+ * <pre>
+ *   // Given
+ *   var MyController = function(obfuscatedScope, obfuscatedRoute) {
+ *     // ...
+ *   }
+ *   // Define function dependencies
+ *   MyController['$inject'] = ['$scope', '$route'];
+ *
+ *   // Then
+ *   expect(injector.annotate(MyController)).toEqual(['$scope', '$route']);
+ * </pre>
+ *
+ * # The array notation
+ *
+ * It is often desirable to inline Injected functions and that's when setting the `$inject` property
+ * is very inconvenient. In these situations using the array notation to specify the dependencies in
+ * a way that survives minification is a better choice:
+ *
+ * <pre>
+ *   // We wish to write this (not minification / obfuscation safe)
+ *   injector.invoke(function($compile, $rootScope) {
+ *     // ...
+ *   });
+ *
+ *   // We are forced to write break inlining
+ *   var tmpFn = function(obfuscatedCompile, obfuscatedRootScope) {
+ *     // ...
+ *   };
+ *   tmpFn.$inject = ['$compile', '$rootScope'];
+ *   injector.invoke(tmpFn);
+ *
+ *   // To better support inline function the inline annotation is supported
+ *   injector.invoke(['$compile', '$rootScope', function(obfCompile, obfRootScope) {
+ *     // ...
+ *   }]);
+ *
+ *   // Therefore
+ *   expect(injector.annotate(
+ *      ['$compile', '$rootScope', function(obfus_$compile, obfus_$rootScope) {}])
+ *    ).toEqual(['$compile', '$rootScope']);
+ * </pre>
+ *

+ * be retrieved as described above.

+ * @returns {Array.<string>} The names of the services which the function requires.

+ * {@link angular.Module}.
+ *
+ * An Angular **service** is a singleton object created by a **service factory**.  These **service
+ * factories** are functions which, in turn, are created by a **service provider**.
+ * The **service providers** are constructor functions. When instantiated they must contain a
+ * property called `$get`, which holds the **service factory** function.
+ *
+ * When you request a service, the {@link AUTO.$injector $injector} is responsible for finding the
+ * correct **service provider**, instantiating it and then calling its `$get` **service factory**
+ * function to get the instance of the **service**.
+ *
+ * Often services have no configuration options and there is no need to add methods to the service
+ * provider.  The provider will be no more than a constructor function with a `$get` property. For
+ * these cases the {@link AUTO.$provide $provide} service has additional helper methods to register
+ * services without specifying a provider.
+ *
+ * * {@link AUTO.$provide#methods_provider provider(provider)} - registers a **service provider** with the

+ *     that will be wrapped in a **service provider** object, whose `$get` property will contain the
+ *     given factory function.
+ * * {@link AUTO.$provide#methods_service service(class)} - registers a **constructor function**, `class` that
+ *     that will be wrapped in a **service provider** object, whose `$get` property will instantiate

+ * Register a **provider function** with the {@link AUTO.$injector $injector}. Provider functions
+ * are constructor functions, whose instances are responsible for "providing" a factory for a
+ * service.
+ *
+ * Service provider names start with the name of the service they provide followed by `Provider`.
+ * For example, the {@link ng.$log $log} service has a provider called
+ * {@link ng.$logProvider $logProvider}.
+ *
+ * Service provider objects can have additional methods which allow configuration of the provider
+ * and its service. Importantly, you can configure what kind of service is created by the `$get`
+ * method, or how that service will act. For example, the {@link ng.$logProvider $logProvider} has a
+ * method {@link ng.$logProvider#debugEnabled debugEnabled}
+ * which lets you specify whether the {@link ng.$log $log} service will log debug messages to the
+ * console or not.
+ *
+ * @param {string} name The name of the instance. NOTE: the provider will be available under `name +
+                        'Provider'` key.
+ * @param {(Object|function())} provider If the provider is:
+ *
+ *   - `Object`: then it should have a `$get` method. The `$get` method will be invoked using
+ *     {@link AUTO.$injector#invoke $injector.invoke()} when an instance needs to be created.
+ *   - `Constructor`: a new instance of the provider will be created using                     
+ *     {@link AUTO.$injector#instantiate $injector.instantiate()}, then treated as `object`.
+ *

+ * **Note:** Any unspecified options will use the default value. You can see the default values below.

+ *
+ *
+ *
+ * ### Directive Definition Object
+ *
+ * The directive definition object provides instructions to the {@link api/ng.$compile
+ * compiler}. The attributes are:
+ *
+ * #### `priority`
+ * When there are multiple directives defined on a single DOM element, sometimes it
+ * is necessary to specify the order in which the directives are applied. The `priority` is used
+ * to sort the directives before their `compile` functions get called. Priority is defined as a
+ * number. Directives with greater numerical `priority` are compiled first. Pre-link functions
+ * are also run in priority order, but post-link functions are run in reverse order. The order
+ * of directives with the same priority is undefined. The default priority is `0`.
+ *
+ * #### `terminal`
+ * If set to true then the current `priority` will be the last set of directives
+ * which will execute (any directives at the current priority will still execute
+ * as the order of execution on same `priority` is undefined).
+ *
+ * #### `scope`
+ * **If set to `true`,** then a new scope will be created for this directive. If multiple directives on the
+ * same element request a new scope, only one new scope is created. The new scope rule does not
+ * apply for the root of the template since the root of the template always gets a new scope.
+ *
+ * **If set to `{}` (object hash),** then a new "isolate" scope is created. The 'isolate' scope differs from
+ * normal scope in that it does not prototypically inherit from the parent scope. This is useful
+ * when creating reusable components, which should not accidentally read or modify data in the
+ * parent scope.
+ *
+ * The 'isolate' scope takes an object hash which defines a set of local scope properties
+ * derived from the parent scope. These local properties are useful for aliasing values for
+ * templates. Locals definition is a hash of local scope property to its source:
+ *
+ * * `@` or `@attr` - bind a local scope property to the value of DOM attribute. The result is
+ *   always a string since DOM attributes are strings. If no `attr` name is specified  then the
+ *   attribute name is assumed to be the same as the local name.
+ *   Given `<widget my-attr="hello {{name}}">` and widget definition
+ *   of `scope: { localName:'@myAttr' }`, then widget scope property `localName` will reflect
+ *   the interpolated value of `hello {{name}}`. As the `name` attribute changes so will the
+ *   `localName` property on the widget scope. The `name` is read from the parent scope (not
+ *   component scope).
+ *
+ * * `=` or `=attr` - set up bi-directional binding between a local scope property and the
+ *   parent scope property of name defined via the value of the `attr` attribute. If no `attr`
+ *   name is specified then the attribute name is assumed to be the same as the local name.
+ *   Given `<widget my-attr="parentModel">` and widget definition of
+ *   `scope: { localModel:'=myAttr' }`, then widget scope property `localModel` will reflect the
+ *   value of `parentModel` on the parent scope. Any changes to `parentModel` will be reflected
+ *   in `localModel` and any changes in `localModel` will reflect in `parentModel`. If the parent
+ *   scope property doesn't exist, it will throw a NON_ASSIGNABLE_MODEL_EXPRESSION exception. You
+ *   can avoid this behavior using `=?` or `=?attr` in order to flag the property as optional.
+ *
+ * * `&` or `&attr` - provides a way to execute an expression in the context of the parent scope.
+ *   If no `attr` name is specified then the attribute name is assumed to be the same as the
+ *   local name. Given `<widget my-attr="count = count + value">` and widget definition of
+ *   `scope: { localFn:'&myAttr' }`, then isolate scope property `localFn` will point to
+ *   a function wrapper for the `count = count + value` expression. Often it's desirable to
+ *   pass data from the isolated scope via an expression and to the parent scope, this can be
+ *   done by passing a map of local variable names and values into the expression wrapper fn.
+ *   For example, if the expression is `increment(amount)` then we can specify the amount value
+ *   by calling the `localFn` as `localFn({amount: 22})`.
+ *
+ *
+ *
+ * #### `controller`
+ * Controller constructor function. The controller is instantiated before the
+ * pre-linking phase and it is shared with other directives (see
+ * `require` attribute). This allows the directives to communicate with each other and augment
+ * each other's behavior. The controller is injectable (and supports bracket notation) with the following locals:
+ *
+ * * `$scope` - Current scope associated with the element
+ * * `$element` - Current element
+ * * `$attrs` - Current attributes object for the element
+ * * `$transclude` - A transclude linking function pre-bound to the correct transclusion scope.
+ *    The scope can be overridden by an optional first argument.
+ *   `function([scope], cloneLinkingFn)`.
+ *
+ *
+ * #### `require`
+ * Require another directive and inject its controller as the fourth argument to the linking function. The
+ * `require` takes a string name (or array of strings) of the directive(s) to pass in. If an array is used, the
+ * injected argument will be an array in corresponding order. If no such directive can be
+ * found, or if the directive does not have a controller, then an error is raised. The name can be prefixed with:
+ *
+ * * (no prefix) - Locate the required controller on the current element. Throw an error if not found.
+ * * `?` - Attempt to locate the required controller or pass `null` to the `link` fn if not found.
+ * * `^` - Locate the required controller by searching the element's parents. Throw an error if not found.
+ * * `?^` - Attempt to locate the required controller by searching the element's parents or pass `null` to the
+ *   `link` fn if not found.
+ *
+ *
+ * #### `controllerAs`
+ * Controller alias at the directive scope. An alias for the controller so it
+ * can be referenced at the directive template. The directive needs to define a scope for this
+ * configuration to be used. Useful in the case when directive is used as component.
+ *
+ *
+ * #### `restrict`
+ * String of subset of `EACM` which restricts the directive to a specific directive
+ * declaration style. If omitted, the default (attributes only) is used.
+ *
+ * * `E` - Element name: `<my-directive></my-directive>`
+ * * `A` - Attribute (default): `<div my-directive="exp"></div>`
+ * * `C` - Class: `<div class="my-directive: exp;"></div>`
+ * * `M` - Comment: `<!-- directive: my-directive exp -->`
+ *
+ *
+ * #### `template`
+ * replace the current element with the contents of the HTML. The replacement process
+ * migrates all of the attributes / classes from the old element to the new one. See the
+ * {@link guide/directive#creating-custom-directives_creating-directives_template-expanding-directive
+ * Directives Guide} for an example.
+ *
+ * You can specify `template` as a string representing the template or as a function which takes
+ * two arguments `tElement` and `tAttrs` (described in the `compile` function api below) and
+ * returns a string value representing the template.
+ *
+ *
+ * #### `templateUrl`
+ * Same as `template` but the template is loaded from the specified URL. Because
+ * the template loading is asynchronous the compilation/linking is suspended until the template
+ * is loaded.
+ *
+ * You can specify `templateUrl` as a string representing the URL or as a function which takes two
+ * arguments `tElement` and `tAttrs` (described in the `compile` function api below) and returns
+ * a string value representing the url.  In either case, the template URL is passed through {@link
+ * api/ng.$sce#methods_getTrustedResourceUrl $sce.getTrustedResourceUrl}.
+ *
+ *
+ * #### `replace`
+ * specify where the template should be inserted. Defaults to `false`.
+ *
+ * * `true` - the template will replace the current element.
+ * * `false` - the template will replace the contents of the current element.
+ *
+ *
+ * #### `transclude`
+ * compile the content of the element and make it available to the directive.
+ * Typically used with {@link api/ng.directive:ngTransclude
+ * ngTransclude}. The advantage of transclusion is that the linking function receives a
+ * transclusion function which is pre-bound to the correct scope. In a typical setup the widget
+ * creates an `isolate` scope, but the transclusion is not a child, but a sibling of the `isolate`
+ * scope. This makes it possible for the widget to have private state, and the transclusion to
+ * be bound to the parent (pre-`isolate`) scope.
+ *
+ * * `true` - transclude the content of the directive.
+ * * `'element'` - transclude the whole element including any directives defined at lower priority.
+ *
+ *
+ * #### `compile`
+ *
+ * <pre>
+ *   function compile(tElement, tAttrs, transclude) { ... }
+ * </pre>
+ *
+ * The compile function deals with transforming the template DOM. Since most directives do not do
+ * template transformation, it is not used often. Examples that require compile functions are
+ * directives that transform template DOM, such as {@link
+ * api/ng.directive:ngRepeat ngRepeat}, or load the contents
+ * asynchronously, such as {@link api/ngRoute.directive:ngView ngView}. The
+ * compile function takes the following arguments.
+ *
+ *   * `tElement` - template element - The element where the directive has been declared. It is
+ *     safe to do template transformation on the element and child elements only.
+ *
+ *   * `tAttrs` - template attributes - Normalized list of attributes declared on this element shared
+ *     between all directive compile functions.
+ *
+ *   * `transclude` -  [*DEPRECATED*!] A transclude linking function: `function(scope, cloneLinkingFn)`
+ *
+ * <div class="alert alert-warning">
+ * **Note:** The template instance and the link instance may be different objects if the template has
+ * been cloned. For this reason it is **not** safe to do anything other than DOM transformations that
+ * apply to all cloned DOM nodes within the compile function. Specifically, DOM listener registration
+ * should be done in a linking function rather than in a compile function.
+ * </div>
+ *
+ * <div class="alert alert-error">
+ * **Note:** The `transclude` function that is passed to the compile function is deprecated, as it
+ *   e.g. does not know about the right outer scope. Please use the transclude function that is passed
+ *   to the link function instead.
+ * </div>
+
+ * A compile function can have a return value which can be either a function or an object.
+ *
+ * * returning a (post-link) function - is equivalent to registering the linking function via the
+ *   `link` property of the config object when the compile function is empty.
+ *
+ * * returning an object with function(s) registered via `pre` and `post` properties - allows you to
+ *   control when a linking function should be called during the linking phase. See info about
+ *   pre-linking and post-linking functions below.
+ *
+ *
+ * #### `link`
+ * This property is used only if the `compile` property is not defined.
+ *
+ * <pre>
+ *   function link(scope, iElement, iAttrs, controller, transcludeFn) { ... }
+ * </pre>
+ *
+ * The link function is responsible for registering DOM listeners as well as updating the DOM. It is
+ * executed after the template has been cloned. This is where most of the directive logic will be
+ * put.
+ *
+ *   * `scope` - {@link api/ng.$rootScope.Scope Scope} - The scope to be used by the
+ *     directive for registering {@link api/ng.$rootScope.Scope#methods_$watch watches}.
+ *
+ *   * `iElement` - instance element - The element where the directive is to be used. It is safe to
+ *     manipulate the children of the element only in `postLink` function since the children have
+ *     already been linked.
+ *
+ *   * `iAttrs` - instance attributes - Normalized list of attributes declared on this element shared
+ *     between all directive linking functions.
+ *
+ *   * `controller` - a controller instance - A controller instance if at least one directive on the
+ *     element defines a controller. The controller is shared among all the directives, which allows
+ *     the directives to use the controllers as a communication channel.
+ *
+ *   * `transcludeFn` - A transclude linking function pre-bound to the correct transclusion scope.
+ *     The scope can be overridden by an optional first argument. This is the same as the `$transclude`
+ *     parameter of directive controllers.
+ *     `function([scope], cloneLinkingFn)`.
+ *
+ *
+ * #### Pre-linking function
+ *
+ * Executed before the child elements are linked. Not safe to do DOM transformation since the
+ * compiler linking function will fail to locate the correct elements for linking.
+ *
+ * #### Post-linking function
+ *
+ * Executed after the child elements are linked. It is safe to do DOM transformation in the post-linking function.
+ *
+ * <a name="Attributes"></a>
+ * ### Attributes
+ *
+ * The {@link api/ng.$compile.directive.Attributes Attributes} object - passed as a parameter in the
+ * `link()` or `compile()` functions. It has a variety of uses.
+ *
+ * accessing *Normalized attribute names:*
+ * Directives like 'ngBind' can be expressed in many ways: 'ng:bind', `data-ng-bind`, or 'x-ng-bind'.
+ * the attributes object allows for normalized access to
+ *   the attributes.
+ *
+ * * *Directive inter-communication:* All directives share the same instance of the attributes
+ *   object which allows the directives to use the attributes object as inter directive
+ *   communication.
+ *
+ * * *Supports interpolation:* Interpolation attributes are assigned to the attribute object
+ *   allowing other directives to read the interpolated value.
+ *
+ * * *Observing interpolated attributes:* Use `$observe` to observe the value changes of attributes
+ *   that contain interpolation (e.g. `src="{{bar}}"`). Not only is this very efficient but it's also
+ *   the only way to easily get the actual value because during the linking phase the interpolation
+ *   hasn't been evaluated yet and so the value is at this time set to `undefined`.
+ *
+ * <pre>
+ * function linkingFn(scope, elm, attrs, ctrl) {
+ *   // get the attribute value
+ *   console.log(attrs.ngModel);
+ *
+ *   // change the attribute
+ *   attrs.$set('ngModel', 'new value');
+ *
+ *   // observe changes to interpolated attribute
+ *   attrs.$observe('ngModel', function(value) {
+ *     console.log('ngModel has changed value to ' + value);
+ *   });
+ * }
+ * </pre>
+ *
+ * Below is an example using `$compileProvider`.
+ *
+ * <div class="alert alert-warning">
+ * **Note**: Typically directives are registered with `module.directive`. The example below is
+ * to illustrate how `$compile` works.

+ * @param {function(angular.Scope[, cloneAttachFn]} transclude function available to directives.
+ * @param {number} maxPriority only apply directives lower then given priority (Only effects the
+ *                 root element(s), not their children)
+ * @returns {function(scope[, cloneAttachFn])} a link function which is used to bind template
+ * (a DOM element/tree) to a scope. Where:
+ *
+ *  * `scope` - A {@link ng.$rootScope.Scope Scope} to bind to.
+ *  * `cloneAttachFn` - If `cloneAttachFn` is provided, then the link function will clone the
+ *  `template` and call the `cloneAttachFn` function allowing the caller to attach the
+ *  cloned elements to the DOM document at the appropriate place. The `cloneAttachFn` is
+ *  called as: <br> `cloneAttachFn(clonedElement, scope)` where:
+ *
+ *      * `clonedElement` - is a clone of the original `element` passed into the compiler.
+ *      * `scope` - is the current scope with which the linking function is working with.
+ *
+ * Calling the linking function returns the element of the template. It is either the original
+ * element passed in, or the clone of the element if the `cloneAttachFn` is provided.
+ *
+ * After linking the view is not updated until after a call to $digest which typically is done by
+ * Angular automatically.
+ *
+ * If you need access to the bound view, there are two ways to do it:
+ *
+ * - If you are not asking the linking function to clone the template, create the DOM element(s)
+ *   before you send them to the compiler and keep this reference around.
+ *   <pre>
+ *     var element = $compile('<p>{{total}}</p>')(scope);
+ *   </pre>
+ *
+ * - if on the other hand, you need the element to be cloned, the view reference from the original
+ *   example would not point to the clone, but rather to the original template that was cloned. In
+ *   this case, you can access the clone via the cloneAttachFn:
+ *   <pre>
+ *     var templateElement = angular.element('<p>{{total}}</p>'),
+ *         scope = ....;
+ *
+ *     var clonedElement = $compile(templateElement)(scope, function(clonedElement, scope) {
+ *       //attach the clone to DOM document at the right place
+ *     });
+ *
+ *     //now we have reference to the cloned DOM via `clonedElement`
+ *   </pre>
+ *
+ *
+ * For information on how the compiler works, see the
+ * {@link guide/compiler Angular HTML Compiler} section of the Developer Guide.

+     * @description
+     * The `$http` service is a core Angular service that facilitates communication with the remote
+     * HTTP servers via the browser's {@link https://developer.mozilla.org/en/xmlhttprequest
+     * XMLHttpRequest} object or via {@link http://en.wikipedia.org/wiki/JSONP JSONP}.
+     *
+     * For unit testing applications that use `$http` service, see
+     * {@link ngMock.$httpBackend $httpBackend mock}.
+     *
+     * For a higher level of abstraction, please check out the {@link ngResource.$resource
+     * $resource} service.
+     *
+     * The $http API is based on the {@link ng.$q deferred/promise APIs} exposed by
+     * the $q service. While for simple usage patterns this doesn't matter much, for advanced usage
+     * it is important to familiarize yourself with these APIs and the guarantees they provide.
+     *
+     *
+     * # General usage
+     * The `$http` service is a function which takes a single argument — a configuration object —
+     * that is used to generate an HTTP request and returns  a {@link ng.$q promise}
+     * with two $http specific methods: `success` and `error`.
+     *
+     * <pre>
+     *   $http({method: 'GET', url: '/someUrl'}).
+     *     success(function(data, status, headers, config) {
+     *       // this callback will be called asynchronously
+     *       // when the response is available
+     *     }).
+     *     error(function(data, status, headers, config) {
+     *       // called asynchronously if an error occurs
+     *       // or server returns response with an error status.
+     *     });
+     * </pre>
+     *
+     * Since the returned value of calling the $http function is a `promise`, you can also use
+     * the `then` method to register callbacks, and these callbacks will receive a single argument –
+     * an object representing the response. See the API signature and type info below for more
+     * details.
+     *
+     * A response status code between 200 and 299 is considered a success status and
+     * will result in the success callback being called. Note that if the response is a redirect,
+     * XMLHttpRequest will transparently follow it, meaning that the error callback will not be
+     * called for such responses.
+     *
+     * # Writing Unit Tests that use $http
+     * When unit testing (using {@link api/ngMock ngMock}), it is necessary to call
+     * {@link api/ngMock.$httpBackend#methods_flush $httpBackend.flush()} to flush each pending
+     * request using trained responses.
+     *
+     * ```
+     * $httpBackend.expectGET(...);
+     * $http.get(...);
+     * $httpBackend.flush();
+     * ```
+     *
+     * # Shortcut methods
+     *
+     * Since all invocations of the $http service require passing in an HTTP method and URL, and
+     * POST/PUT requests require request data to be provided as well, shortcut methods
+     * were created:
+     *
+     * <pre>
+     *   $http.get('/someUrl').success(successCallback);
+     *   $http.post('/someUrl', data).success(successCallback);
+     * </pre>
+     *
+     * Complete list of shortcut methods:
+     *
+     * - {@link ng.$http#methods_get $http.get}
+     * - {@link ng.$http#methods_head $http.head}
+     * - {@link ng.$http#methods_post $http.post}
+     * - {@link ng.$http#methods_put $http.put}
+     * - {@link ng.$http#methods_delete $http.delete}
+     * - {@link ng.$http#methods_jsonp $http.jsonp}
+     *
+     *
+     * # Setting HTTP Headers
+     *
+     * The $http service will automatically add certain HTTP headers to all requests. These defaults
+     * can be fully configured by accessing the `$httpProvider.defaults.headers` configuration
+     * object, which currently contains this default configuration:
+     *
+     * - `$httpProvider.defaults.headers.common` (headers that are common for all requests):
+     *   - `Accept: application/json, text/plain, * / *`
+     * - `$httpProvider.defaults.headers.post`: (header defaults for POST requests)
+     *   - `Content-Type: application/json`
+     * - `$httpProvider.defaults.headers.put` (header defaults for PUT requests)
+     *   - `Content-Type: application/json`
+     *
+     * To add or overwrite these defaults, simply add or remove a property from these configuration
+     * objects. To add headers for an HTTP method other than POST or PUT, simply add a new object
+     * with the lowercased HTTP method name as the key, e.g.
+     * `$httpProvider.defaults.headers.get = { 'My-Header' : 'value' }.
+     *
+     * The defaults can also be set at runtime via the `$http.defaults` object in the same
+     * fashion. For example:
+     *
+     * ```
+     * module.run(function($http) {
+     *   $http.defaults.headers.common.Authentication = 'Basic YmVlcDpib29w'
+     * });
+     * ```
+     *
+     * In addition, you can supply a `headers` property in the config object passed when
+     * calling `$http(config)`, which overrides the defaults without changing them globally.
+     *
+     *
+     * # Transforming Requests and Responses
+     *
+     * Both requests and responses can be transformed using transform functions. By default, Angular
+     * applies these transformations:
+     *
+     * Request transformations:
+     *
+     * - If the `data` property of the request configuration object contains an object, serialize it
+     *   into JSON format.
+     *
+     * Response transformations:
+     *
+     *  - If XSRF prefix is detected, strip it (see Security Considerations section below).
+     *  - If JSON response is detected, deserialize it using a JSON parser.
+     *
+     * To globally augment or override the default transforms, modify the
+     * `$httpProvider.defaults.transformRequest` and `$httpProvider.defaults.transformResponse`
+     * properties. These properties are by default an array of transform functions, which allows you
+     * to `push` or `unshift` a new transformation function into the transformation chain. You can
+     * also decide to completely override any default transformations by assigning your
+     * transformation functions to these properties directly without the array wrapper.  These defaults
+     * are again available on the $http factory at run-time, which may be useful if you have run-time
+     * services you wish to be involved in your transformations.
+     *
+     * Similarly, to locally override the request/response transforms, augment the
+     * `transformRequest` and/or `transformResponse` properties of the configuration object passed
+     * into `$http`.
+     *
+     *
+     * # Caching
+     *
+     * To enable caching, set the request configuration `cache` property to `true` (to use default
+     * cache) or to a custom cache object (built with {@link ng.$cacheFactory `$cacheFactory`}).
+     * When the cache is enabled, `$http` stores the response from the server in the specified
+     * cache. The next time the same request is made, the response is served from the cache without
+     * sending a request to the server.
+     *
+     * Note that even if the response is served from cache, delivery of the data is asynchronous in
+     * the same way that real requests are.
+     *
+     * If there are multiple GET requests for the same URL that should be cached using the same
+     * cache, but the cache is not populated yet, only one request to the server will be made and
+     * the remaining requests will be fulfilled using the response from the first request.
+     *
+     * You can change the default cache to a new object (built with
+     * {@link ng.$cacheFactory `$cacheFactory`}) by updating the
+     * {@link ng.$http#properties_defaults `$http.defaults.cache`} property. All requests who set
+     * their `cache` property to `true` will now use this cache object.
+     *
+     * If you set the default cache to `false` then only requests that specify their own custom
+     * cache object will be cached.
+     *
+     * # Interceptors
+     *
+     * Before you start creating interceptors, be sure to understand the
+     * {@link ng.$q $q and deferred/promise APIs}.
+     *
+     * For purposes of global error handling, authentication, or any kind of synchronous or
+     * asynchronous pre-processing of request or postprocessing of responses, it is desirable to be
+     * able to intercept requests before they are handed to the server and
+     * responses before they are handed over to the application code that
+     * initiated these requests. The interceptors leverage the {@link ng.$q
+     * promise APIs} to fulfill this need for both synchronous and asynchronous pre-processing.
+     *
+     * The interceptors are service factories that are registered with the `$httpProvider` by
+     * adding them to the `$httpProvider.interceptors` array. The factory is called and
+     * injected with dependencies (if specified) and returns the interceptor.
+     *
+     * There are two kinds of interceptors (and two kinds of rejection interceptors):
+     *
+     *   * `request`: interceptors get called with http `config` object. The function is free to
+     *     modify the `config` or create a new one. The function needs to return the `config`
+     *     directly or as a promise.
+     *   * `requestError`: interceptor gets called when a previous interceptor threw an error or
+     *     resolved with a rejection.
+     *   * `response`: interceptors get called with http `response` object. The function is free to
+     *     modify the `response` or create a new one. The function needs to return the `response`
+     *     directly or as a promise.
+     *   * `responseError`: interceptor gets called when a previous interceptor threw an error or
+     *     resolved with a rejection.
+     *

+     * # Security Considerations
+     *
+     * When designing web applications, consider security threats from:
+     *
+     * - {@link http://haacked.com/archive/2008/11/20/anatomy-of-a-subtle-json-vulnerability.aspx
+     *   JSON vulnerability}
+     * - {@link http://en.wikipedia.org/wiki/Cross-site_request_forgery XSRF}
+     *
+     * Both server and the client must cooperate in order to eliminate these threats. Angular comes
+     * pre-configured with strategies that address these issues, but for this to work backend server
+     * cooperation is required.
+     *
+     * ## JSON Vulnerability Protection
+     *
+     * A {@link http://haacked.com/archive/2008/11/20/anatomy-of-a-subtle-json-vulnerability.aspx
+     * JSON vulnerability} allows third party website to turn your JSON resource URL into
+     * {@link http://en.wikipedia.org/wiki/JSONP JSONP} request under some conditions. To
+     * counter this your server can prefix all JSON requests with following string `")]}',\n"`.
+     * Angular will automatically strip the prefix before processing it as JSON.
+     *
+     * For example if your server needs to return:
+     * <pre>
+     * ['one','two']
+     * </pre>
+     *
+     * which is vulnerable to attack, your server can return:
+     * <pre>
+     * )]}',
+     * ['one','two']
+     * </pre>
+     *
+     * Angular will strip the prefix, before processing the JSON.
+     *
+     *
+     * ## Cross Site Request Forgery (XSRF) Protection
+     *
+     * {@link http://en.wikipedia.org/wiki/Cross-site_request_forgery XSRF} is a technique by which
+     * an unauthorized site can gain your user's private data. Angular provides a mechanism
+     * to counter XSRF. When performing XHR requests, the $http service reads a token from a cookie
+     * (by default, `XSRF-TOKEN`) and sets it as an HTTP header (`X-XSRF-TOKEN`). Since only
+     * JavaScript that runs on your domain could read the cookie, your server can be assured that
+     * the XHR came from JavaScript running on your domain. The header will not be set for
+     * cross-domain requests.
+     *
+     * To take advantage of this, your server needs to set a token in a JavaScript readable session
+     * cookie called `XSRF-TOKEN` on the first HTTP GET request. On subsequent XHR requests the
+     * server can verify that the cookie matches `X-XSRF-TOKEN` HTTP header, and therefore be sure
+     * that only JavaScript running on your domain could have sent the request. The token must be
+     * unique for each user and must be verifiable by the server (to prevent the JavaScript from
+     * making up its own tokens). We recommend that the token is a digest of your site's
+     * authentication cookie with a {@link https://en.wikipedia.org/wiki/Salt_(cryptography) salt}
+     * for added security.
+     *
+     * The name of the headers can be specified using the xsrfHeaderName and xsrfCookieName
+     * properties of either $httpProvider.defaults at config-time, $http.defaults at run-time,
+     * or the per-request config object.
+     *
+     *
+     * @param {object} config Object describing the request to be made and how it should be
+     *    processed. The object has following properties:
+     *
+     *    - **method** – `{string}` – HTTP method (e.g. 'GET', 'POST', etc)
+     *    - **url** – `{string}` – Absolute or relative URL of the resource that is being requested.
+     *    - **params** – `{Object.<string|Object>}` – Map of strings or objects which will be turned
+     *      to `?key1=value1&key2=value2` after the url. If the value is not a string, it will be
+     *      JSONified.
+     *    - **data** – `{string|Object}` – Data to be sent as the request message data.
+     *    - **headers** – `{Object}` – Map of strings or functions which return strings representing
+     *      HTTP headers to send to the server. If the return value of a function is null, the
+     *      header will not be sent.
+     *    - **xsrfHeaderName** – `{string}` – Name of HTTP header to populate with the XSRF token.
+     *    - **xsrfCookieName** – `{string}` – Name of cookie containing the XSRF token.
+     *    - **transformRequest** –
+     *      `{function(data, headersGetter)|Array.<function(data, headersGetter)>}` –
+     *      transform function or an array of such functions. The transform function takes the http
+     *      request body and headers and returns its transformed (typically serialized) version.
+     *    - **transformResponse** –
+     *      `{function(data, headersGetter)|Array.<function(data, headersGetter)>}` –
+     *      transform function or an array of such functions. The transform function takes the http
+     *      response body and headers and returns its transformed (typically deserialized) version.
+     *    - **cache** – `{boolean|Cache}` – If true, a default $http cache will be used to cache the
+     *      GET request, otherwise if a cache instance built with
+     *      {@link ng.$cacheFactory $cacheFactory}, this cache will be used for
+     *      caching.
+     *    - **timeout** – `{number|Promise}` – timeout in milliseconds, or {@link ng.$q promise}
+     *      that should abort the request when resolved.
+     *    - **withCredentials** - `{boolean}` - whether to to set the `withCredentials` flag on the
+     *      XHR object. See {@link https://developer.mozilla.org/en/http_access_control#section_5
+     *      requests with credentials} for more information.
+     *    - **responseType** - `{string}` - see {@link
+     *      https://developer.mozilla.org/en-US/docs/DOM/XMLHttpRequest#responseType requestType}.
+     *
+     * @returns {HttpPromise} Returns a {@link ng.$q promise} object with the
+     *   standard `then` method and two http specific methods: `success` and `error`. The `then`
+     *   method takes two arguments a success and an error callback which will be called with a
+     *   response object. The `success` and `error` methods take a single argument - a function that
+     *   will be called when the request succeeds or fails respectively. The arguments passed into
+     *   these functions are destructured representation of the response object passed into the
+     *   `then` method. The response object has these properties:
+     *
+     *   - **data** – `{string|Object}` – The response body transformed with the transform
+     *     functions.
+     *   - **status** – `{number}` – HTTP status code of the response.
+     *   - **headers** – `{function([headerName])}` – Header getter function.
+     *   - **config** – `{Object}` – The configuration object that was used to generate the request.
+     *
+     * @property {Array.<Object>} pendingRequests Array of config objects for currently pending
+     *   requests. This is primarily meant to be used for debugging purposes.

+// Sandboxing Angular Expressions
+// ------------------------------
+// Angular expressions are generally considered safe because these expressions only have direct
+// access to $scope and locals. However, one can obtain the ability to execute arbitrary JS code by
+// obtaining a reference to native JS functions such as the Function constructor.
+//
+// As an example, consider the following Angular expression:
+//
+//   {}.toString.constructor(alert("evil JS code"))
+//
+// We want to prevent this type of access. For the sake of performance, during the lexing phase we
+// disallow any "dotted" access to any member named "constructor".
+//
+// For reflective calls (a[b]) we check that the value of the lookup is not the Function constructor
+// while evaluating the expression, which is a stronger but more expensive test. Since reflective
+// calls are expensive anyway, this is not such a big deal compared to static dereferencing.
+//
+// This sandboxing technique is not perfect and doesn't aim to be. The goal is to prevent exploits
+// against the expression language, but not to prevent exploits that were enabled by exposing
+// sensitive JavaScript or browser apis on Scope. Exposing such objects on a Scope is never a good
+// practice and therefore we are not even trying to protect against interaction with an object
+// explicitly exposed in this way.
+//
+// A developer could foil the name check by aliasing the Function constructor under a different
+// name on the scope.
+//
+// In general, it is not possible to access a Window object from an angular expression unless a
+// window or some DOM object that has a reference to window is published onto a Scope.

+   * @description
+   *
+   * **This feature is deprecated, see deprecation notes below for more info**
+   *
+   * If set to true (default is false), $parse will unwrap promises automatically when a promise is
+   * found at any part of the expression. In other words, if set to true, the expression will always
+   * result in a non-promise value.
+   *
+   * While the promise is unresolved, it's treated as undefined, but once resolved and fulfilled,
+   * the fulfillment value is used in place of the promise while evaluating the expression.
+   *
+   * **Deprecation notice**
+   *
+   * This is a feature that didn't prove to be wildly useful or popular, primarily because of the
+   * dichotomy between data access in templates (accessed as raw values) and controller code
+   * (accessed as promises).
+   *
+   * In most code we ended up resolving promises manually in controllers anyway and thus unifying
+   * the model access there.
+   *
+   * Other downsides of automatic promise unwrapping:
+   *
+   * - when building components it's often desirable to receive the raw promises
+   * - adds complexity and slows down expression evaluation
+   * - makes expression code pre-generation unattractive due to the amount of code that needs to be
+   *   generated
+   * - makes IDE auto-completion and tool support hard
+   *
+   * **Warning Logs**
+   *
+   * If the unwrapping is enabled, Angular will log a warning about each expression that unwraps a
+   * promise (to reduce the noise, each expression is logged only once). To disable this logging use
+   * `$parseProvider.logPromiseWarnings(false)` api.

+/**
+ * @ngdoc service
+ * @name ng.$q
+ * @requires $rootScope
+ *
+ * @description
+ * A promise/deferred implementation inspired by [Kris Kowal's Q](https://github.com/kriskowal/q).
+ *
+ * [The CommonJS Promise proposal](http://wiki.commonjs.org/wiki/Promises) describes a promise as an
+ * interface for interacting with an object that represents the result of an action that is
+ * performed asynchronously, and may or may not be finished at any given point in time.
+ *
+ * From the perspective of dealing with error handling, deferred and promise APIs are to
+ * asynchronous programming what `try`, `catch` and `throw` keywords are to synchronous programming.
+ *
+ * <pre>
+ *   // for the purpose of this example let's assume that variables `$q`, `scope` and `okToGreet`
+ *   // are available in the current lexical scope (they could have been injected or passed in).
+ * 
+ *   function asyncGreet(name) {
+ *     var deferred = $q.defer();
+ *
+ *     setTimeout(function() {
+ *       // since this fn executes async in a future turn of the event loop, we need to wrap
+ *       // our code into an $apply call so that the model changes are properly observed.
+ *       scope.$apply(function() {
+ *         deferred.notify('About to greet ' + name + '.');
+ *
+ *         if (okToGreet(name)) {
+ *           deferred.resolve('Hello, ' + name + '!');
+ *         } else {
+ *           deferred.reject('Greeting ' + name + ' is not allowed.');
+ *         }
+ *       });
+ *     }, 1000);
+ *
+ *     return deferred.promise;
+ *   }
+ *
+ *   var promise = asyncGreet('Robin Hood');
+ *   promise.then(function(greeting) {
+ *     alert('Success: ' + greeting);
+ *   }, function(reason) {
+ *     alert('Failed: ' + reason);
+ *   }, function(update) {
+ *     alert('Got notification: ' + update);
+ *   });
+ * </pre>
+ *
+ * At first it might not be obvious why this extra complexity is worth the trouble. The payoff
+ * comes in the way of guarantees that promise and deferred APIs make, see
+ * https://github.com/kriskowal/uncommonjs/blob/master/promises/specification.md.
+ *
+ * Additionally the promise api allows for composition that is very hard to do with the
+ * traditional callback ([CPS](http://en.wikipedia.org/wiki/Continuation-passing_style)) approach.
+ * For more on this please see the [Q documentation](https://github.com/kriskowal/q) especially the
+ * section on serial or parallel joining of promises.
+ *
+ *
+ * # The Deferred API
+ *
+ * A new instance of deferred is constructed by calling `$q.defer()`.
+ *
+ * The purpose of the deferred object is to expose the associated Promise instance as well as APIs
+ * that can be used for signaling the successful or unsuccessful completion, as well as the status
+ * of the task.
+ *
+ * **Methods**
+ *
+ * - `resolve(value)` – resolves the derived promise with the `value`. If the value is a rejection
+ *   constructed via `$q.reject`, the promise will be rejected instead.
+ * - `reject(reason)` – rejects the derived promise with the `reason`. This is equivalent to
+ *   resolving it with a rejection constructed via `$q.reject`.
+ * - `notify(value)` - provides updates on the status of the promise's execution. This may be called
+ *   multiple times before the promise is either resolved or rejected.
+ *
+ * **Properties**
+ *
+ * - promise – `{Promise}` – promise object associated with this deferred.
+ *
+ *
+ * # The Promise API
+ *
+ * A new promise instance is created when a deferred instance is created and can be retrieved by
+ * calling `deferred.promise`.
+ *
+ * The purpose of the promise object is to allow for interested parties to get access to the result
+ * of the deferred task when it completes.
+ *
+ * **Methods**
+ *
+ * - `then(successCallback, errorCallback, notifyCallback)` – regardless of when the promise was or
+ *   will be resolved or rejected, `then` calls one of the success or error callbacks asynchronously
+ *   as soon as the result is available. The callbacks are called with a single argument: the result
+ *   or rejection reason. Additionally, the notify callback may be called zero or more times to
+ *   provide a progress indication, before the promise is resolved or rejected.
+ *
+ *   This method *returns a new promise* which is resolved or rejected via the return value of the
+ *   `successCallback`, `errorCallback`. It also notifies via the return value of the
+ *   `notifyCallback` method. The promise can not be resolved or rejected from the notifyCallback
+ *   method.
+ *
+ * - `catch(errorCallback)` – shorthand for `promise.then(null, errorCallback)`
+ *
+ * - `finally(callback)` – allows you to observe either the fulfillment or rejection of a promise,
+ *   but to do so without modifying the final value. This is useful to release resources or do some
+ *   clean-up that needs to be done whether the promise was rejected or resolved. See the [full
+ *   specification](https://github.com/kriskowal/q/wiki/API-Reference#promisefinallycallback) for
+ *   more information.
+ *
+ *   Because `finally` is a reserved word in JavaScript and reserved keywords are not supported as
+ *   property names by ES3, you'll need to invoke the method like `promise['finally'](callback)` to
+ *   make your code IE8 compatible.
+ *
+ * # Chaining promises
+ *
+ * Because calling the `then` method of a promise returns a new derived promise, it is easily
+ * possible to create a chain of promises:
+ *
+ * <pre>
+ *   promiseB = promiseA.then(function(result) {
+ *     return result + 1;
+ *   });
+ *
+ *   // promiseB will be resolved immediately after promiseA is resolved and its value
+ *   // will be the result of promiseA incremented by 1
+ * </pre>
+ *
+ * It is possible to create chains of any length and since a promise can be resolved with another
+ * promise (which will defer its resolution further), it is possible to pause/defer resolution of
+ * the promises at any point in the chain. This makes it possible to implement powerful APIs like
+ * $http's response interceptors.
+ *
+ *
+ * # Differences between Kris Kowal's Q and $q
+ *
+ *  There are two main differences:
+ *
+ * - $q is integrated with the {@link ng.$rootScope.Scope} Scope model observation
+ *   mechanism in angular, which means faster propagation of resolution or rejection into your
+ *   models and avoiding unnecessary browser repaints, which would result in flickering UI.
+ * - Q has many more features than $q, but that comes at a cost of bytes. $q is tiny, but contains
+ *   all the important functionality needed for common async tasks.
+ *
+ *  # Testing
+ *
+ *  <pre>
+ *    it('should simulate promise', inject(function($q, $rootScope) {
+ *      var deferred = $q.defer();
+ *      var promise = deferred.promise;
+ *      var resolvedValue;
+ *
+ *      promise.then(function(value) { resolvedValue = value; });
+ *      expect(resolvedValue).toBeUndefined();
+ *
+ *      // Simulate resolving of promise
+ *      deferred.resolve(123);
+ *      // Note that the 'then' function does not get called synchronously.
+ *      // This is because we want the promise API to always be async, whether or not
+ *      // it got called synchronously or asynchronously.
+ *      expect(resolvedValue).toBeUndefined();
+ *
+ *      // Propagate promise resolution to 'then' functions using $apply().
+ *      $rootScope.$apply();
+ *      expect(resolvedValue).toEqual(123);
+ *    }));
+ *  </pre>

+ * DESIGN NOTES
+ *
+ * The design decisions behind the scope are heavily favored for speed and memory consumption.
+ *
+ * The typical use of scope is to watch the expressions, which most of the time return the same
+ * value as last time so we optimize the operation.
+ *
+ * Closures construction is expensive in terms of speed as well as memory:
+ *   - No closures, instead use prototypical inheritance for API
+ *   - Internal state needs to be stored on scope directly, which means that private state is
+ *     exposed as $$____ properties
+ *
+ * Loop operations are optimized by using while(count--) { ... }
+ *   - this means that in order to keep the same order of execution as addition we have to add
+ *     items to the array at the beginning (shift) instead of at the end (push)
+ *
+ * Child scopes are created and removed often
+ *   - Using an array would be slow since inserts in middle are expensive so we use linked list
+ *
+ * There are few watches then a lot of observers. This is why you don't want the observer to be
+ * implemented in the same way as watch. Watch requires return of initialization function which
+ * are expensive to construct.

+       * - The `listener` is called only when the value from the current `watchExpression` and the
+       *   previous call to `watchExpression` are not equal (with the exception of the initial run,
+       *   see below). The inequality is determined according to

+       *   the {@link angular.copy} function is used. It also means that watching complex options
+       *   will have adverse memory and performance implications.
+       * - The watch `listener` may change the model, which may trigger other `listener`s to fire.
+       *   This is achieved by rerunning the watchers until no changes are detected. The rerun
+       *   iteration limit is 10 to prevent an infinite loop deadlock.
+       *
+       *
+       * If you want to be notified whenever {@link ng.$rootScope.Scope#methods_$digest $digest} is called,
+       * you can register a `watchExpression` function with no `listener`. (Since `watchExpression`
+       * can execute multiple times per {@link ng.$rootScope.Scope#methods_$digest $digest} cycle when a
+       * change is detected, be prepared for multiple calls to your listener.)
+       *
+       * After a watcher is registered with the scope, the `listener` fn is called asynchronously
+       * (via {@link ng.$rootScope.Scope#methods_$evalAsync $evalAsync}) to initialize the
+       * watcher. In rare cases, this is undesirable because the listener is called when the result
+       * of `watchExpression` didn't change. To detect this scenario within the `listener` fn, you
+       * can compare the `newVal` and `oldVal`. If these two values are identical (`===`) then the
+       * listener was called due to initialization.
+       *
+       * The example below contains an illustration of using a function as your $watch listener

+       *
+       * - The `obj` collection is observed via standard $watch operation and is examined on every
+       *   call to $digest() to see if any items have been added, removed, or moved.
+       * - The `listener` is called whenever anything within the `obj` has changed. Examples include

+       * @param {function(newCollection, oldCollection, scope)} listener a callback function that is
+       *    fired with both the `newCollection` and `oldCollection` as parameters.
+       *    The `newCollection` object is the newly modified data obtained from the `obj` expression
+       *    and the `oldCollection` object is a copy of the former collection data.

+       * a {@link ng.$compileProvider#methods_directive directives}), which will force a `$digest()`.
+       *
+       * If you want to be notified whenever `$digest()` is called,

+ * work because `$sce` delegates to `$sceDelegate` for these operations.
+ *
+ * Refer {@link ng.$sceDelegateProvider $sceDelegateProvider} to configure this service.
+ *
+ * The default instance of `$sceDelegate` should work out of the box with little pain.  While you
+ * can override it completely to change the behavior of `$sce`, the common case would
+ * involve configuring the {@link ng.$sceDelegateProvider $sceDelegateProvider} instead by setting

+ *
+ * @description
+ *
+ * `$sce` is a service that provides Strict Contextual Escaping services to AngularJS.
+ *
+ * # Strict Contextual Escaping
+ *
+ * Strict Contextual Escaping (SCE) is a mode in which AngularJS requires bindings in certain
+ * contexts to result in a value that is marked as safe to use for that context.  One example of
+ * such a context is binding arbitrary html controlled by the user via `ng-bind-html`.  We refer
+ * to these contexts as privileged or SCE contexts.
+ *
+ * As of version 1.2, Angular ships with SCE enabled by default.
+ *
+ * Note:  When enabled (the default), IE8 in quirks mode is not supported.  In this mode, IE8 allows
+ * one to execute arbitrary javascript by the use of the expression() syntax.  Refer
+ * <http://blogs.msdn.com/b/ie/archive/2008/10/16/ending-expressions.aspx> to learn more about them.
+ * You can ensure your document is in standards mode and not quirks mode by adding `<!doctype html>`
+ * to the top of your HTML document.
+ *
+ * SCE assists in writing code in way that (a) is secure by default and (b) makes auditing for
+ * security vulnerabilities such as XSS, clickjacking, etc. a lot easier.
+ *
+ * Here's an example of a binding in a privileged context:
+ *
+ * <pre class="prettyprint">
+ *     <input ng-model="userHtml">
+ *     <div ng-bind-html="userHtml">
+ * </pre>
+ *
+ * Notice that `ng-bind-html` is bound to `userHtml` controlled by the user.  With SCE
+ * disabled, this application allows the user to render arbitrary HTML into the DIV.
+ * In a more realistic example, one may be rendering user comments, blog articles, etc. via
+ * bindings.  (HTML is just one example of a context where rendering user controlled input creates
+ * security vulnerabilities.)
+ *
+ * For the case of HTML, you might use a library, either on the client side, or on the server side,
+ * to sanitize unsafe HTML before binding to the value and rendering it in the document.
+ *
+ * How would you ensure that every place that used these types of bindings was bound to a value that
+ * was sanitized by your library (or returned as safe for rendering by your server?)  How can you
+ * ensure that you didn't accidentally delete the line that sanitized the value, or renamed some
+ * properties/fields and forgot to update the binding to the sanitized value?
+ *
+ * To be secure by default, you want to ensure that any such bindings are disallowed unless you can
+ * determine that something explicitly says it's safe to use a value for binding in that
+ * context.  You can then audit your code (a simple grep would do) to ensure that this is only done
+ * for those values that you can easily tell are safe - because they were received from your server,
+ * sanitized by your library, etc.  You can organize your codebase to help with this - perhaps
+ * allowing only the files in a specific directory to do this.  Ensuring that the internal API
+ * exposed by that code doesn't markup arbitrary values as safe then becomes a more manageable task.
+ *
+ * In the case of AngularJS' SCE service, one uses {@link ng.$sce#methods_trustAs $sce.trustAs} 
+ * (and shorthand methods such as {@link ng.$sce#methods_trustAsHtml $sce.trustAsHtml}, etc.) to
+ * obtain values that will be accepted by SCE / privileged contexts.
+ *
+ *
+ * ## How does it work?
+ *
+ * In privileged contexts, directives and code will bind to the result of {@link ng.$sce#methods_getTrusted
+ * $sce.getTrusted(context, value)} rather than to the value directly.  Directives use {@link
+ * ng.$sce#methods_parse $sce.parseAs} rather than `$parse` to watch attribute bindings, which performs the
+ * {@link ng.$sce#methods_getTrusted $sce.getTrusted} behind the scenes on non-constant literals.
+ *
+ * As an example, {@link ng.directive:ngBindHtml ngBindHtml} uses {@link
+ * ng.$sce#methods_parseAsHtml $sce.parseAsHtml(binding expression)}.  Here's the actual code (slightly
+ * simplified):
+ *
+ * <pre class="prettyprint">
+ *   var ngBindHtmlDirective = ['$sce', function($sce) {
+ *     return function(scope, element, attr) {
+ *       scope.$watch($sce.parseAsHtml(attr.ngBindHtml), function(value) {
+ *         element.html(value || '');
+ *       });
+ *     };
+ *   }];
+ * </pre>
+ *
+ * ## Impact on loading templates
+ *
+ * This applies both to the {@link ng.directive:ngInclude `ng-include`} directive as well as
+ * `templateUrl`'s specified by {@link guide/directive directives}.
+ *
+ * By default, Angular only loads templates from the same domain and protocol as the application
+ * document.  This is done by calling {@link ng.$sce#methods_getTrustedResourceUrl
+ * $sce.getTrustedResourceUrl} on the template URL.  To load templates from other domains and/or
+ * protocols, you may either either {@link ng.$sceDelegateProvider#methods_resourceUrlWhitelist whitelist
+ * them} or {@link ng.$sce#methods_trustAsResourceUrl wrap it} into a trusted value.
+ *
+ * *Please note*:
+ * The browser's
+ * {@link https://code.google.com/p/browsersec/wiki/Part2#Same-origin_policy_for_XMLHttpRequest
+ * Same Origin Policy} and {@link http://www.w3.org/TR/cors/ Cross-Origin Resource Sharing (CORS)}
+ * policy apply in addition to this and may further restrict whether the template is successfully
+ * loaded.  This means that without the right CORS policy, loading templates from a different domain
+ * won't work on all browsers.  Also, loading templates from `file://` URL does not work on some
+ * browsers.
+ *
+ * ## This feels like too much overhead for the developer?
+ *
+ * It's important to remember that SCE only applies to interpolation expressions.
+ *
+ * If your expressions are constant literals, they're automatically trusted and you don't need to
+ * call `$sce.trustAs` on them (remember to include the `ngSanitize` module) (e.g.
+ * `<div ng-bind-html="'<b>implicitly trusted</b>'"></div>`) just works.
+ *
+ * Additionally, `a[href]` and `img[src]` automatically sanitize their URLs and do not pass them
+ * through {@link ng.$sce#methods_getTrusted $sce.getTrusted}.  SCE doesn't play a role here.
+ *
+ * The included {@link ng.$sceDelegate $sceDelegate} comes with sane defaults to allow you to load
+ * templates in `ng-include` from your application's domain without having to even know about SCE.
+ * It blocks loading templates from other domains or loading templates over http from an https
+ * served document.  You can change these by setting your own custom {@link
+ * ng.$sceDelegateProvider#methods_resourceUrlWhitelist whitelists} and {@link
+ * ng.$sceDelegateProvider#methods_resourceUrlBlacklist blacklists} for matching such URLs.
+ *
+ * This significantly reduces the overhead.  It is far easier to pay the small overhead and have an
+ * application that's secure and can be audited to verify that with much more ease than bolting
+ * security onto an application later.
+ *
+ * <a name="contexts"></a>
+ * ## What trusted context types are supported?
+ *
+ * | Context             | Notes          |
+ * |---------------------|----------------|
+ * | `$sce.HTML`         | For HTML that's safe to source into the application.  The {@link ng.directive:ngBindHtml ngBindHtml} directive uses this context for bindings. |
+ * | `$sce.CSS`          | For CSS that's safe to source into the application.  Currently unused.  Feel free to use it in your own directives. |
+ * | `$sce.URL`          | For URLs that are safe to follow as links.  Currently unused (`<a href=` and `<img src=` sanitize their urls and don't consititute an SCE context. |
+ * | `$sce.RESOURCE_URL` | For URLs that are not only safe to follow as links, but whose contens are also safe to include in your application.  Examples include `ng-include`, `src` / `ngSrc` bindings for tags other than `IMG` (e.g. `IFRAME`, `OBJECT`, etc.)  <br><br>Note that `$sce.RESOURCE_URL` makes a stronger statement about the URL than `$sce.URL` does and therefore contexts requiring values trusted for `$sce.RESOURCE_URL` can be used anywhere that values trusted for `$sce.URL` are required. |
+ * | `$sce.JS`           | For JavaScript that is safe to execute in your application's context.  Currently unused.  Feel free to use it in your own directives. |
+ *
+ * ## Format of items in {@link ng.$sceDelegateProvider#methods_resourceUrlWhitelist resourceUrlWhitelist}/{@link ng.$sceDelegateProvider#methods_resourceUrlBlacklist Blacklist} <a name="resourceUrlPatternItem"></a>
+ *
+ *  Each element in these arrays must be one of the following:
+ *
+ *  - **'self'**
+ *    - The special **string**, `'self'`, can be used to match against all URLs of the **same
+ *      domain** as the application document using the **same protocol**.
+ *  - **String** (except the special value `'self'`)
+ *    - The string is matched against the full *normalized / absolute URL* of the resource
+ *      being tested (substring matches are not good enough.)
+ *    - There are exactly **two wildcard sequences** - `*` and `**`.  All other characters
+ *      match themselves.
+ *    - `*`: matches zero or more occurances of any character other than one of the following 6
+ *      characters: '`:`', '`/`', '`.`', '`?`', '`&`' and ';'.  It's a useful wildcard for use
+ *      in a whitelist.
+ *    - `**`: matches zero or more occurances of *any* character.  As such, it's not
+ *      not appropriate to use in for a scheme, domain, etc. as it would match too much.  (e.g.
+ *      http://**.example.com/ would match http://evil.com/?ignore=.example.com/ and that might
+ *      not have been the intention.)  It's usage at the very end of the path is ok.  (e.g.
+ *      http://foo.example.com/templates/**).
+ *  - **RegExp** (*see caveat below*)
+ *    - *Caveat*:  While regular expressions are powerful and offer great flexibility,  their syntax
+ *      (and all the inevitable escaping) makes them *harder to maintain*.  It's easy to
+ *      accidentally introduce a bug when one updates a complex expression (imho, all regexes should
+ *      have good test coverage.).  For instance, the use of `.` in the regex is correct only in a
+ *      small number of cases.  A `.` character in the regex used when matching the scheme or a
+ *      subdomain could be matched against a `:` or literal `.` that was likely not intended.   It
+ *      is highly recommended to use the string patterns and only fall back to regular expressions
+ *      if they as a last resort.
+ *    - The regular expression must be an instance of RegExp (i.e. not a string.)  It is
+ *      matched against the **entire** *normalized / absolute URL* of the resource being tested
+ *      (even when the RegExp did not have the `^` and `$` codes.)  In addition, any flags
+ *      present on the RegExp (such as multiline, global, ignoreCase) are ignored.
+ *    - If you are generating your JavaScript from some other templating engine (not
+ *      recommended, e.g. in issue [#4006](https://github.com/angular/angular.js/issues/4006)),
+ *      remember to escape your regular expression (and be aware that you might need more than
+ *      one level of escaping depending on your templating engine and the way you interpolated
+ *      the value.)  Do make use of your platform's escaping mechanism as it might be good
+ *      enough before coding your own.  e.g. Ruby has
+ *      [Regexp.escape(str)](http://www.ruby-doc.org/core-2.0.0/Regexp.html#method-c-escape)
+ *      and Python has [re.escape](http://docs.python.org/library/re.html#re.escape).
+ *      Javascript lacks a similar built in function for escaping.  Take a look at Google
+ *      Closure library's [goog.string.regExpEscape(s)](
+ *      http://docs.closure-library.googlecode.com/git/closure_goog_string_string.js.source.html#line962).
+ *
+ * Refer {@link ng.$sceDelegateProvider $sceDelegateProvider} for an example.

+ * ## Can I disable SCE completely?
+ *
+ * Yes, you can.  However, this is strongly discouraged.  SCE gives you a lot of security benefits
+ * for little coding overhead.  It will be much harder to take an SCE disabled application and
+ * either secure it on your own or enable SCE at a later stage.  It might make sense to disable SCE
+ * for cases where you have a lot of existing code that was written before SCE was introduced and
+ * you're migrating them a module at a time.
+ *
+ * That said, here's how you can completely disable SCE:
+ *
+ * <pre class="prettyprint">
+ *   angular.module('myAppWithSceDisabledmyApp', []).config(function($sceProvider) {
+ *     // Completely disable SCE.  For demonstration purposes only!
+ *     // Do not use in new projects.
+ *     $sceProvider.enabled(false);
+ *   });
+ * </pre>

+  /* Design notes on the default implementation for SCE.
+   *
+   * The API contract for the SCE delegate
+   * -------------------------------------
+   * The SCE delegate object must provide the following 3 methods:
+   *
+   * - trustAs(contextEnum, value)
+   *     This method is used to tell the SCE service that the provided value is OK to use in the
+   *     contexts specified by contextEnum.  It must return an object that will be accepted by
+   *     getTrusted() for a compatible contextEnum and return this value.
+   *
+   * - valueOf(value)
+   *     For values that were not produced by trustAs(), return them as is.  For values that were
+   *     produced by trustAs(), return the corresponding input value to trustAs.  Basically, if
+   *     trustAs is wrapping the given values into some type, this operation unwraps it when given
+   *     such a value.
+   *
+   * - getTrusted(contextEnum, value)
+   *     This function should return the a value that is safe to use in the context specified by
+   *     contextEnum or throw and exception otherwise.
+   *
+   * NOTE: This contract deliberately does NOT state that values returned by trustAs() must be
+   * opaque or wrapped in some holder object.  That happens to be an implementation detail.  For
+   * instance, an implementation could maintain a registry of all trusted objects by context.  In
+   * such a case, trustAs() would return the same object that was passed in.  getTrusted() would
+   * return the same object passed in if it was found in the registry under a compatible context or
+   * throw an exception otherwise.  An implementation might only wrap values some of the time based
+   * on some criteria.  getTrusted() might return a value and not throw an exception for special
+   * constants or objects even if not wrapped.  All such implementations fulfill this contract.
+   *
+   *
+   * A note on the inheritance model for SCE contexts
+   * ------------------------------------------------
+   * I've used inheritance and made RESOURCE_URL wrapped types a subtype of URL wrapped types.  This
+   * is purely an implementation details.
+   *
+   * The contract is simply this:
+   *
+   *     getTrusted($sce.RESOURCE_URL, value) succeeding implies that getTrusted($sce.URL, value)
+   *     will also succeed.
+   *
+   * Inheritance happens to capture this in a natural way.  In some future, we
+   * may not use inheritance anymore.  That is OK because no code outside of
+   * sce.js and sceSpecs.js would need to be aware of this detail.

+ *
+ * Implementation Notes for non-IE browsers
+ * ----------------------------------------
+ * Assigning a URL to the href property of an anchor DOM node, even one attached to the DOM,
+ * results both in the normalizing and parsing of the URL.  Normalizing means that a relative
+ * URL will be resolved into an absolute URL in the context of the application document.
+ * Parsing means that the anchor node's host, hostname, protocol, port, pathname and related
+ * properties are all populated to reflect the normalized URL.  This approach has wide
+ * compatibility - Safari 1+, Mozilla 1+, Opera 7+,e etc.  See
+ * http://www.aptana.com/reference/html/api/HTMLAnchorElement.html
+ *
+ * Implementation Notes for IE
+ * ---------------------------
+ * IE >= 8 and <= 10 normalizes the URL when assigned to the anchor node similar to the other
+ * browsers.  However, the parsed components will not be set if the URL assigned did not specify
+ * them.  (e.g. if you assign a.href = "foo", then a.protocol, a.host, etc. will be empty.)  We
+ * work around that by performing the parsing in a 2nd step by taking a previously normalized
+ * URL (e.g. by assigning to a.href) and assigning it a.href again.  This correctly populates the
+ * properties such as protocol, hostname, port, etc.
+ *
+ * IE7 does not normalize the URL when assigned to an anchor node.  (Apparently, it does, if one
+ * uses the inner HTML approach to assign the URL as part of an HTML snippet -
+ * http://stackoverflow.com/a/472729)  However, setting img[src] does normalize the URL.
+ * Unfortunately, setting img[src] to something like "javascript:foo" on IE throws an exception.
+ * Since the primary usage for normalizing URLs is to sanitize such URLs, we can't use that
+ * method and IE < 8 is unsupported.

+ * Selects a subset of items from `array` and returns it as a new array.
+ *
+ * @param {Array} array The source array.
+ * @param {string|Object|function()} expression The predicate to be used for selecting items from
+ *   `array`.
+ *
+ *   Can be one of:
+ *
+ *   - `string`: The string is evaluated as an expression and the resulting value is used for substring match against
+ *     the contents of the `array`. All strings or objects with string properties in `array` that contain this string
+ *     will be returned. The predicate can be negated by prefixing the string with `!`.
+ *
+ *   - `Object`: A pattern object can be used to filter specific properties on objects contained
+ *     by `array`. For example `{name:"M", phone:"1"}` predicate will return an array of items
+ *     which have property `name` containing "M" and property `phone` containing "1". A special
+ *     property name `$` can be used (as in `{$:"text"}`) to accept a match against any
+ *     property of the object. That's equivalent to the simple substring match with a `string`
+ *     as described above.
+ *
+ *   - `function(value)`: A predicate function can be used to write arbitrary filters. The function is
+ *     called for each element of `array`. The final result is an array of those elements that
+ *     the predicate returned true for.
+ *
+ * @param {function(actual, expected)|true|undefined} comparator Comparator which is used in
+ *     determining if the expected value (from the filter expression) and actual value (from
+ *     the object in the array) should be considered a match.
+ *
+ *   Can be one of:
+ *
+ *     - `function(actual, expected)`:
+ *       The function will be given the object value and the predicate value to compare and
+ *       should return true if the item should be included in filtered result.
+ *
+ *     - `true`: A shorthand for `function(actual, expected) { return angular.equals(expected, actual)}`.
+ *       this is essentially strict comparison of expected and actual.
+ *
+ *     - `false|undefined`: A short hand for a function which will look for a substring match in case
+ *       insensitive way.

+ *   {@link guide/i18n localizable formats}:
+ *
+ *   * `'medium'`: equivalent to `'MMM d, y h:mm:ss a'` for en_US locale

+ *   * `'shortTime'`: equivalent to `'h:mm a'` for en_US locale (e.g. 12:05 pm)
+ *
+ *   `format` string can contain literal values. These need to be quoted with single quotes (e.g.
+ *   `"h 'in the morning'"`). In order to output single quote, use two single quotes in a sequence
+ *   (e.g. `"h 'o''clock'"`).
+ *
+ * @param {(Date|number|string)} date Date to format either as Date object, milliseconds (string or
+ *    number) or various ISO 8601 datetime string formats (e.g. yyyy-MM-ddTHH:mm:ss.SSSZ and its
+ *    shorter versions like yyyy-MM-ddTHH:mmZ, yyyy-MM-dd or yyyyMMddTHHmmssZ). If no timezone is
+ *    specified in the string input, the time is considered to be in the local timezone.
+ * @param {string=} format Formatting rules (see Description). If not specified,
+ *    `mediumDate` is used.

+ *
+ * If the `name` attribute is specified, the form controller is published onto the current scope under
+ * this name.
+ *
+ * # Alias: {@link ng.directive:ngForm `ngForm`}
+ *
+ * In Angular forms can be nested. This means that the outer form is valid when all of the child
+ * forms are valid as well. However, browsers do not allow nesting of `<form>` elements, so
+ * Angular provides the {@link ng.directive:ngForm `ngForm`} directive which behaves identically to
+ * `<form>` but can be nested.  This allows you to have nested forms, which is very useful when
+ * using Angular validation directives in forms that are dynamically generated using the
+ * {@link ng.directive:ngRepeat `ngRepeat`} directive. Since you cannot dynamically generate the `name`
+ * attribute of input elements using interpolation, you have to wrap each set of repeated inputs in an
+ * `ngForm` directive and nest these in an outer `form` element.
+ *
+ *
+ * # CSS classes
+ *  - `ng-valid` is set if the form is valid.
+ *  - `ng-invalid` is set if the form is invalid.
+ *  - `ng-pristine` is set if the form is pristine.
+ *  - `ng-dirty` is set if the form is dirty.
+ *
+ *
+ * # Submitting a form and preventing the default action
+ *
+ * Since the role of forms in client-side Angular applications is different than in classical
+ * roundtrip apps, it is desirable for the browser not to translate the form submission into a full
+ * page reload that sends the data to the server. Instead some javascript logic should be triggered
+ * to handle the form submission in an application-specific way.
+ *
+ * For this reason, Angular prevents the default action (form submission to the server) unless the
+ * `<form>` element has an `action` attribute specified.
+ *
+ * You can use one of the following two ways to specify what javascript method should be called when
+ * a form is submitted:
+ *
+ * - {@link ng.directive:ngSubmit ngSubmit} directive on the form element
+ * - {@link ng.directive:ngClick ngClick} directive on the first
+  *  button or input field of type submit (input[type=submit])
+ *
+ * To prevent double execution of the handler, use only one of the {@link ng.directive:ngSubmit ngSubmit}
+ * or {@link ng.directive:ngClick ngClick} directives.
+ * This is because of the following form submission rules in the HTML specification:
+ *
+ * - If a form has only one input field then hitting enter in this field triggers form submit
+ * (`ngSubmit`)
+ * - if a form has 2+ input fields and no buttons or input[type=submit] then hitting enter
+ * doesn't trigger submit
+ * - if a form has one or more input fields and one or more buttons or input[type=submit] then
+ * hitting enter in any of the input fields will trigger the click handler on the *first* button or
+ * input[type=submit] (`ngClick`) *and* a submit handler on the enclosing form (`ngSubmit`)
+ *
+ * @param {string=} name Name of the form. If specified, the form controller will be published into
+ *                       related scope, under this name.

+ * `NgModelController` provides API for the `ng-model` directive. The controller contains
+ * services for data-binding, validation, CSS updates, and value formatting and parsing. It
+ * purposefully does not contain any logic which deals with DOM rendering or listening to
+ * DOM events. Such DOM related logic should be provided by other directives which make use of
+ * `NgModelController` for data-binding.
+ *
+ * ## Custom Control Example
+ * This example shows how to use `NgModelController` with a custom control to achieve
+ * data-binding. Notice how different directives (`contenteditable`, `ng-model`, and `required`)
+ * collaborate together to achieve the desired result.
+ *
+ * Note that `contenteditable` is an HTML5 attribute, which tells the browser to let the element
+ * contents be edited in place by the user.  This will not work on older browsers.
+ *
+ * <example module="customControl">
+    <file name="style.css">
+      [contenteditable] {
+        border: 1px solid black;
+        background-color: white;

+ * which is created and exposed by this directive.
+ *
+ * `ngModel` is responsible for:
+ *
+ * - Binding the view into the model, which other directives such as `input`, `textarea` or `select`
+ *   require.
+ * - Providing validation behavior (i.e. required, number, email, url).
+ * - Keeping the state of the control (valid/invalid, dirty/pristine, validation errors).
+ * - Setting related css classes on the element (`ng-valid`, `ng-invalid`, `ng-dirty`, `ng-pristine`).
+ * - Registering the control with its parent {@link ng.directive:form form}.
+ *
+ * Note: `ngModel` will try to bind to the property given by evaluating the expression on the
+ * current scope. If the property doesn't already exist on this scope, it will be created
+ * implicitly and added to the scope.
+ *
+ * For best practices on using `ngModel`, see:

+ * It is preferrable to use `ngBind` instead of `{{ expression }}` when a template is momentarily

+ * under {@link ng.$sce#Example Strict Contextual Escaping (SCE)}.

+ *
+ * @description
+ * The `ngCloak` directive is used to prevent the Angular html template from being briefly
+ * displayed by the browser in its raw (uncompiled) form while your application is loading. Use this
+ * directive to avoid the undesirable flicker effect caused by the html template display.
+ *
+ * The directive can be applied to the `<body>` element, but the preferred usage is to apply
+ * multiple `ngCloak` directives to small portions of the page to permit progressive rendering
+ * of the browser view.
+ *
+ * `ngCloak` works in cooperation with the following css rule embedded within `angular.js` and
+ * `angular.min.js`.
+ * For CSP mode please add `angular-csp.css` to your html file (see {@link ng.directive:ngCsp ngCsp}).
+ *
+ * <pre>
+ * [ng\:cloak], [ng-cloak], [data-ng-cloak], [x-ng-cloak], .ng-cloak, .x-ng-cloak {
+ *   display: none !important;
+ * }
+ * </pre>
+ *
+ * When this css rule is loaded by the browser, all html elements (including their children) that
+ * are tagged with the `ngCloak` directive are hidden. When Angular encounters this directive
+ * during the compilation of the template it deletes the `ngCloak` element attribute, making
+ * the compiled element visible.
+ *
+ * For the best result, the `angular.js` script must be loaded in the head section of the html
+ * document; alternatively, the css rule above must be included in the external stylesheet of the
+ * application.
+ *
+ * Legacy browsers, like IE7, do not provide attribute selector support (added in CSS 2.1) so they
+ * cannot match the `[ng\:cloak]` selector. To work around this limitation, you must add the css
+ * class `ng-cloak` in addition to the `ngCloak` directive as shown in the example below.
+ *
+ * @element ANY

+ * @ngdoc directive
+ * @name ng.directive:ngController
+ *
+ * @description
+ * The `ngController` directive attaches a controller class to the view. This is a key aspect of how angular
+ * supports the principles behind the Model-View-Controller design pattern.
+ *
+ * MVC components in angular:
+ *
+ * * Model — The Model is scope properties; scopes are attached to the DOM where scope properties
+ *   are accessed through bindings.
+ * * View — The template (HTML with data bindings) that is rendered into the View.
+ * * Controller — The `ngController` directive specifies a Controller class; the class contains business
+ *   logic behind the application to decorate the scope with functions and values
+ *
+ * Note that you can also attach controllers to the DOM by declaring it in a route definition
+ * via the {@link ngRoute.$route $route} service. A common mistake is to declare the controller
+ * again using `ng-controller` in the template itself.  This will cause the controller to be attached
+ * and executed twice.
+ *
+ * @element ANY
+ * @scope
+ * @param {expression} ngController Name of a globally accessible constructor function or an
+ *     {@link guide/expression expression} that on the current scope evaluates to a
+ *     constructor function. The controller instance can be published into a scope property
+ *     by specifying `as propertyName`.
+ *
+ * @example
+ * Here is a simple form for editing user contact information. Adding, removing, clearing, and
+ * greeting are methods declared on the controller (see source tab). These methods can
+ * easily be called from the angular markup. Notice that the scope becomes the `this` for the
+ * controller's instance. This allows for easy access to the view data from the controller. Also
+ * notice that any changes to the data are automatically reflected in the View without the need
+ * for a manual update. The example is shown in two different declaration styles you may use
+ * according to preference.

+ *
+ * @element html
+ * @description
+ * Enables [CSP (Content Security Policy)](https://developer.mozilla.org/en/Security/CSP) support.
+ *
+ * This is necessary when developing things like Google Chrome Extensions.
+ *
+ * CSP forbids apps to use `eval` or `Function(string)` generated functions (among other things).
+ * For us to be compatible, we just need to implement the "getterFn" in $parse without violating
+ * any of these restrictions.
+ *
+ * AngularJS uses `Function(string)` generated functions as a speed optimization. Applying the `ngCsp`
+ * directive will cause Angular to use CSP compatibility mode. When this mode is on AngularJS will
+ * evaluate all expressions up to 30% slower than in non-CSP mode, but no security violations will
+ * be raised.
+ *
+ * CSP forbids JavaScript to inline stylesheet rules. In non CSP mode Angular automatically
+ * includes some CSS rules (e.g. {@link ng.directive:ngCloak ngCloak}).
+ * To make those directives work in CSP mode, include the `angular-csp.css` manually.
+ *
+ * In order to use this feature put the `ngCsp` directive on the root element of the application.
+ *
+ * *Note: This directive is only available in the `ng-csp` and `data-ng-csp` attribute form.*
+ *
+ * @example
+ * This example shows how to apply the `ngCsp` directive to the `html` tag.
+   <pre>
+     <!doctype html>
+     <html ng-app ng-csp>
+     ...
+     ...
+     </html>
+   </pre>
+ */
+
+// ngCsp is not implemented as a proper directive any more, because we need it be processed while we bootstrap
+// the system (before $parse is instantiated), for this reason we just have a csp() fn that looks for ng-csp attribute
+// anywhere in the current doc

+ * @ngdoc directive
+ * @name ng.directive:ngIf
+ * @restrict A
+ *
+ * @description
+ * The `ngIf` directive removes or recreates a portion of the DOM tree based on an
+ * {expression}. If the expression assigned to `ngIf` evaluates to a false
+ * value then the element is removed from the DOM, otherwise a clone of the
+ * element is reinserted into the DOM.
+ *
+ * `ngIf` differs from `ngShow` and `ngHide` in that `ngIf` completely removes and recreates the
+ * element in the DOM rather than changing its visibility via the `display` css property.  A common
+ * case when this difference is significant is when using css selectors that rely on an element's
+ * position within the DOM, such as the `:first-child` or `:last-child` pseudo-classes.
+ *
+ * Note that when an element is removed using `ngIf` its scope is destroyed and a new scope
+ * is created when the element is restored.  The scope created within `ngIf` inherits from
+ * its parent scope using
+ * {@link https://github.com/angular/angular.js/wiki/The-Nuances-of-Scope-Prototypal-Inheritance prototypal inheritance}.
+ * An important implication of this is if `ngModel` is used within `ngIf` to bind to
+ * a javascript primitive defined in the parent scope. In this case any modifications made to the
+ * variable within the child scope will override (hide) the value in the parent scope.
+ *
+ * Also, `ngIf` recreates elements using their compiled state. An example of this behavior
+ * is if an element's class attribute is directly modified after it's compiled, using something like
+ * jQuery's `.addClass()` method, and the element is later removed. When `ngIf` recreates the element
+ * the added class will be lost because the original compiled state is used to regenerate the element.
+ *
+ * Additionally, you can provide animations via the `ngAnimate` module to animate the `enter`
+ * and `leave` effects.
+ *
+ * @animations
+ * enter - happens just after the ngIf contents change and a new DOM element is created and injected into the ngIf container
+ * leave - happens just before the ngIf contents are removed from the DOM
+ *
+ * @element ANY
+ * @scope
+ * @priority 600
+ * @param {expression} ngIf If the {@link guide/expression expression} is falsy then

+ *
+ * @example
+  <example animations="true">

+ *
+ * @description
+ * Fetches, compiles and includes an external HTML fragment.
+ *
+ * By default, the template URL is restricted to the same domain and protocol as the
+ * application document. This is done by calling {@link ng.$sce#methods_getTrustedResourceUrl
+ * $sce.getTrustedResourceUrl} on it. To load templates from other domains or protocols
+ * you may either {@link ng.$sceDelegateProvider#methods_resourceUrlWhitelist whitelist them} or
+ * {@link ng.$sce#methods_trustAsResourceUrl wrap them} as trusted values. Refer to Angular's {@link
+ * ng.$sce Strict Contextual Escaping}.
+ *
+ * In addition, the browser's
+ * {@link https://code.google.com/p/browsersec/wiki/Part2#Same-origin_policy_for_XMLHttpRequest
+ * Same Origin Policy} and {@link http://www.w3.org/TR/cors/ Cross-Origin Resource Sharing
+ * (CORS)} policy may further restrict whether the template is successfully loaded.
+ * For example, `ngInclude` won't work for cross-domain requests on all browsers and for `file://`
+ * access on some browsers.
+ *
+ * @animations
+ * enter - animation is used to bring new content into the browser.
+ * leave - animation is used to animate existing content away.
+ *
+ * The enter and leave animation occur concurrently.
+ *
+ * @scope
+ * @priority 400
+ *
+ * @param {string} ngInclude|src angular expression evaluating to URL. If the source is a string constant,
+ *                 make sure you wrap it in quotes, e.g. `src="'myPartialTemplate.html'"`.
+ * @param {string=} onload Expression to evaluate when a new partial is loaded.
+ *
+ * @param {string=} autoscroll Whether `ngInclude` should call {@link ng.$anchorScroll
+ *                  $anchorScroll} to scroll the viewport after the content is loaded.
+ *
+ *                  - If the attribute is not set, disable scrolling.
+ *                  - If the attribute is set without value, enable scrolling.

+/**
+ * @ngdoc directive
+ * @name ng.directive:ngPluralize
+ * @restrict EA
+ *
+ * @description
+ * # Overview
+ * `ngPluralize` is a directive that displays messages according to en-US localization rules.
+ * These rules are bundled with angular.js, but can be overridden
+ * (see {@link guide/i18n Angular i18n} dev guide). You configure ngPluralize directive
+ * by specifying the mappings between
+ * {@link http://unicode.org/repos/cldr-tmp/trunk/diff/supplemental/language_plural_rules.html
+ * plural categories} and the strings to be displayed.
+ *
+ * # Plural categories and explicit number rules
+ * There are two
+ * {@link http://unicode.org/repos/cldr-tmp/trunk/diff/supplemental/language_plural_rules.html
+ * plural categories} in Angular's default en-US locale: "one" and "other".
+ *
+ * While a plural category may match many numbers (for example, in en-US locale, "other" can match
+ * any number that is not 1), an explicit number rule can only match one number. For example, the
+ * explicit number rule for "3" matches the number 3. There are examples of plural categories
+ * and explicit number rules throughout the rest of this documentation.
+ *
+ * # Configuring ngPluralize
+ * You configure ngPluralize by providing 2 attributes: `count` and `when`.
+ * You can also provide an optional attribute, `offset`.
+ *
+ * The value of the `count` attribute can be either a string or an {@link guide/expression
+ * Angular expression}; these are evaluated on the current scope for its bound value.
+ *
+ * The `when` attribute specifies the mappings between plural categories and the actual
+ * string to be displayed. The value of the attribute should be a JSON object.
+ *
+ * The following example shows how to configure ngPluralize:
+ *
+ * <pre>
+ * <ng-pluralize count="personCount"
+                 when="{'0': 'Nobody is viewing.',
+ *                      'one': '1 person is viewing.',
+ *                      'other': '{} people are viewing.'}">
+ * </ng-pluralize>
+ *</pre>
+ *
+ * In the example, `"0: Nobody is viewing."` is an explicit number rule. If you did not
+ * specify this rule, 0 would be matched to the "other" category and "0 people are viewing"
+ * would be shown instead of "Nobody is viewing". You can specify an explicit number rule for
+ * other numbers, for example 12, so that instead of showing "12 people are viewing", you can
+ * show "a dozen people are viewing".
+ *
+ * You can use a set of closed braces (`{}`) as a placeholder for the number that you want substituted
+ * into pluralized strings. In the previous example, Angular will replace `{}` with
+ * <span ng-non-bindable>`{{personCount}}`</span>. The closed braces `{}` is a placeholder
+ * for <span ng-non-bindable>{{numberExpression}}</span>.
+ *
+ * # Configuring ngPluralize with offset
+ * The `offset` attribute allows further customization of pluralized text, which can result in
+ * a better user experience. For example, instead of the message "4 people are viewing this document",
+ * you might display "John, Kate and 2 others are viewing this document".
+ * The offset attribute allows you to offset a number by any desired value.
+ * Let's take a look at an example:
+ *
+ * <pre>
+ * <ng-pluralize count="personCount" offset=2
+ *               when="{'0': 'Nobody is viewing.',
+ *                      '1': '{{person1}} is viewing.',
+ *                      '2': '{{person1}} and {{person2}} are viewing.',
+ *                      'one': '{{person1}}, {{person2}} and one other person are viewing.',
+ *                      'other': '{{person1}}, {{person2}} and {} other people are viewing.'}">
+ * </ng-pluralize>
+ * </pre>
+ *
+ * Notice that we are still using two plural categories(one, other), but we added
+ * three explicit number rules 0, 1 and 2.
+ * When one person, perhaps John, views the document, "John is viewing" will be shown.
+ * When three people view the document, no explicit number rule is found, so
+ * an offset of 2 is taken off 3, and Angular uses 1 to decide the plural category.
+ * In this case, plural category 'one' is matched and "John, Marry and one other person are viewing"
+ * is shown.
+ *
+ * Note that when you specify offsets, you must provide explicit number rules for
+ * numbers from 0 up to and including the offset. If you use an offset of 3, for example,
+ * you must provide explicit number rules for 0, 1, 2 and 3. You must also provide plural strings for
+ * plural categories "one" and "other".
+ *
+ * @param {string|expression} count The variable to be bounded to.
+ * @param {string} when The mapping between plural category to its corresponding strings.
+ * @param {number=} offset Offset to deduct from the total number.
+ *
+ * @example
+    <doc:example>
+      <doc:source>
+        <script>
+          function Ctrl($scope) {

+/**
+ * @ngdoc directive
+ * @name ng.directive:ngRepeat
+ *
+ * @description
+ * The `ngRepeat` directive instantiates a template once per item from a collection. Each template
+ * instance gets its own scope, where the given loop variable is set to the current collection item,
+ * and `$index` is set to the item index or key.
+ *
+ * Special properties are exposed on the local scope of each template instance, including:
+ *
+ * | Variable  | Type            | Details                                                                     |
+ * |-----------|-----------------|-----------------------------------------------------------------------------|
+ * | `$index`  | {@type number}  | iterator offset of the repeated element (0..length-1)                       |
+ * | `$first`  | {@type boolean} | true if the repeated element is first in the iterator.                      |
+ * | `$middle` | {@type boolean} | true if the repeated element is between the first and last in the iterator. |
+ * | `$last`   | {@type boolean} | true if the repeated element is last in the iterator.                       |
+ * | `$even`   | {@type boolean} | true if the iterator position `$index` is even (otherwise false).           |
+ * | `$odd`    | {@type boolean} | true if the iterator position `$index` is odd (otherwise false).            |
+ *
+ * Creating aliases for these properties is possible with {@link api/ng.directive:ngInit `ngInit`}.
+ * This may be useful when, for instance, nesting ngRepeats.
+ *
+ * # Special repeat start and end points
+ * To repeat a series of elements instead of just one parent element, ngRepeat (as well as other ng directives) supports extending
+ * the range of the repeater by defining explicit start and end points by using **ng-repeat-start** and **ng-repeat-end** respectively.
+ * The **ng-repeat-start** directive works the same as **ng-repeat**, but will repeat all the HTML code (including the tag it's defined on)
+ * up to and including the ending HTML tag where **ng-repeat-end** is placed.
+ *
+ * The example below makes use of this feature:
+ * <pre>
+ *   <header ng-repeat-start="item in items">
+ *     Header {{ item }}
+ *   </header>
+ *   <div class="body">
+ *     Body {{ item }}
+ *   </div>
+ *   <footer ng-repeat-end>
+ *     Footer {{ item }}
+ *   </footer>
+ * </pre>
+ *
+ * And with an input of {@type ['A','B']} for the items variable in the example above, the output will evaluate to:
+ * <pre>
+ *   <header>
+ *     Header A
+ *   </header>
+ *   <div class="body">
+ *     Body A
+ *   </div>
+ *   <footer>
+ *     Footer A
+ *   </footer>
+ *   <header>
+ *     Header B
+ *   </header>
+ *   <div class="body">
+ *     Body B
+ *   </div>
+ *   <footer>
+ *     Footer B
+ *   </footer>
+ * </pre>
+ *
+ * The custom start and end points for ngRepeat also support all other HTML directive syntax flavors provided in AngularJS (such
+ * as **data-ng-repeat-start**, **x-ng-repeat-start** and **ng:repeat-start**).
+ *
+ * @animations
+ * enter - when a new item is added to the list or when an item is revealed after a filter
+ * leave - when an item is removed from the list or when an item is filtered out
+ * move - when an adjacent item is filtered out causing a reorder or when the item contents are reordered
+ *
+ * @element ANY
+ * @scope
+ * @priority 1000
+ * @param {repeat_expression} ngRepeat The expression indicating how to enumerate a collection. These
+ *   formats are currently supported:
+ *
+ *   * `variable in expression` – where variable is the user defined loop variable and `expression`
+ *     is a scope expression giving the collection to enumerate.
+ *
+ *     For example: `album in artist.albums`.
+ *
+ *   * `(key, value) in expression` – where `key` and `value` can be any user defined identifiers,
+ *     and `expression` is the scope expression giving the collection to enumerate.
+ *
+ *     For example: `(name, age) in {'adam':10, 'amalie':12}`.
+ *
+ *   * `variable in expression track by tracking_expression` – You can also provide an optional tracking function
+ *     which can be used to associate the objects in the collection with the DOM elements. If no tracking function
+ *     is specified the ng-repeat associates elements by identity in the collection. It is an error to have
+ *     more than one tracking function to resolve to the same key. (This would mean that two distinct objects are
+ *     mapped to the same DOM element, which is not possible.)  Filters should be applied to the expression,
+ *     before specifying a tracking expression.
+ *
+ *     For example: `item in items` is equivalent to `item in items track by $id(item)'. This implies that the DOM elements
+ *     will be associated by item identity in the array.
+ *
+ *     For example: `item in items track by $id(item)`. A built in `$id()` function can be used to assign a unique
+ *     `$$hashKey` property to each item in the array. This property is then used as a key to associated DOM elements
+ *     with the corresponding item in the array by identity. Moving the same object in array would move the DOM
+ *     element in the same way in the DOM.
+ *
+ *     For example: `item in items track by item.id` is a typical pattern when the items come from the database. In this
+ *     case the object identity does not matter. Two objects are considered equivalent as long as their `id`
+ *     property is same.
+ *
+ *     For example: `item in items | filter:searchText track by item.id` is a pattern that might be used to apply a filter
+ *     to items in conjunction with a tracking expression.
+ *
+ * @example
+ * This example initializes the scope to a list of names and
+ * then uses `ngRepeat` to display every person:

+/**
+ * @ngdoc directive
+ * @name ng.directive:ngShow
+ *
+ * @description
+ * The `ngShow` directive shows or hides the given HTML element based on the expression
+ * provided to the ngShow attribute. The element is shown or hidden by removing or adding
+ * the `ng-hide` CSS class onto the element. The `.ng-hide` CSS class is predefined
+ * in AngularJS and sets the display style to none (using an !important flag).
+ * For CSP mode please add `angular-csp.css` to your html file (see {@link ng.directive:ngCsp ngCsp}).
+ *
+ * <pre>
+ * <!-- when $scope.myValue is truthy (element is visible) -->
+ * <div ng-show="myValue"></div>
+ *
+ * <!-- when $scope.myValue is falsy (element is hidden) -->
+ * <div ng-show="myValue" class="ng-hide"></div>
+ * </pre>
+ *
+ * When the ngShow expression evaluates to false then the ng-hide CSS class is added to the class attribute
+ * on the element causing it to become hidden. When true, the ng-hide CSS class is removed
+ * from the element causing the element not to appear hidden.
+ *
+ * ## Why is !important used?
+ *
+ * You may be wondering why !important is used for the .ng-hide CSS class. This is because the `.ng-hide` selector
+ * can be easily overridden by heavier selectors. For example, something as simple
+ * as changing the display style on a HTML list item would make hidden elements appear visible.
+ * This also becomes a bigger issue when dealing with CSS frameworks.
+ *
+ * By using !important, the show and hide behavior will work as expected despite any clash between CSS selector
+ * specificity (when !important isn't used with any conflicting styles). If a developer chooses to override the
+ * styling to change how to hide an element then it is just a matter of using !important in their own CSS code.
+ *
+ * ### Overriding .ng-hide
+ *
+ * If you wish to change the hide behavior with ngShow/ngHide then this can be achieved by
+ * restating the styles for the .ng-hide class in CSS:
+ * <pre>
+ * .ng-hide {
+ *   //!annotate CSS Specificity|Not to worry, this will override the AngularJS default...
+ *   display:block!important;
+ *
+ *   //this is just another form of hiding an element
+ *   position:absolute;
+ *   top:-9999px;
+ *   left:-9999px;
+ * }
+ * </pre>
+ *
+ * Just remember to include the important flag so the CSS override will function.
+ *
+ * <div class="alert alert-warning">
+ * **Note:** Here is a list of values that ngShow will consider as a falsy value (case insensitive):<br />
+ * "f" / "0" / "false" / "no" / "n" / "[]"
+ * </div>
+ * 
+ * ## A note about animations with ngShow
+ *
+ * Animations in ngShow/ngHide work with the show and hide events that are triggered when the directive expression
+ * is true and false. This system works like the animation system present with ngClass except that
+ * you must also include the !important flag to override the display property
+ * so that you can perform an animation when the element is hidden during the time of the animation.
+ *
+ * <pre>
+ * //
+ * //a working example can be found at the bottom of this page
+ * //
+ * .my-element.ng-hide-add, .my-element.ng-hide-remove {
+ *   transition:0.5s linear all;
+ *   display:block!important;
+ * }
+ *
+ * .my-element.ng-hide-add { ... }

+ * .my-element.ng-hide-remove { ... }
+ * .my-element.ng-hide-remove.ng-hide-remove-active { ... }
+ * </pre>
+ *
+ * @animations
+ * addClass: .ng-hide - happens after the ngShow expression evaluates to a truthy value and the just before contents are set to visible
+ * removeClass: .ng-hide - happens after the ngShow expression evaluates to a non truthy value and just before the contents are set to hidden
+ *
+ * @element ANY
+ * @param {expression} ngShow If the {@link guide/expression expression} is truthy
+ *     then the element is shown or hidden respectively.

+ *
+ * @description
+ * The `ngSwitch` directive is used to conditionally swap DOM structure on your template based on a scope expression.
+ * Elements within `ngSwitch` but without `ngSwitchWhen` or `ngSwitchDefault` directives will be preserved at the location
+ * as specified in the template.
+ *
+ * The directive itself works similar to ngInclude, however, instead of downloading template code (or loading it
+ * from the template cache), `ngSwitch` simply chooses one of the nested elements and makes it visible based on which element
+ * matches the value obtained from the evaluated expression. In other words, you define a container element
+ * (where you place the directive), place an expression on the **`on="..."` attribute**
+ * (or the **`ng-switch="..."` attribute**), define any inner elements inside of the directive and place
+ * a when attribute per element. The when attribute is used to inform ngSwitch which element to display when the on
+ * expression is evaluated. If a matching expression is not found via a when attribute then an element with the default
+ * attribute is displayed.
+ *
+ * <div class="alert alert-info">
+ * Be aware that the attribute values to match against cannot be expressions. They are interpreted
+ * as literal string values to match against.
+ * For example, **`ng-switch-when="someVal"`** will match against the string `"someVal"` not against the
+ * value of the expression `$scope.someVal`.
+ * </div>
+
+ * @animations
+ * enter - happens after the ngSwitch contents change and the matched child element is placed inside the container
+ * leave - happens just after the ngSwitch contents change and just before the former contents are removed from the DOM

+ * @param {*} ngSwitch|on expression to match against <tt>ng-switch-when</tt>.
+ * @paramDescription
+ * On child elements add:

+ * * `ngSwitchWhen`: the case statement to match against. If match then this
+ *   case will be displayed. If the same match appears multiple times, all the
+ *   elements will be displayed.
+ * * `ngSwitchDefault`: the default case when no other case match. If there
+ *   are multiple default cases, all of them will be displayed when no other

+ *
+ * @description
+ * HTML `SELECT` element with angular data-binding.
+ *
+ * # `ngOptions`
+ *
+ * The `ngOptions` attribute can be used to dynamically generate a list of `<option>`
+ * elements for the `<select>` element using the array or object obtained by evaluating the
+ * `ngOptions` comprehension_expression.
+ *
+ * When an item in the `<select>` menu is selected, the array element or object property
+ * represented by the selected option will be bound to the model identified by the `ngModel`
+ * directive.
+ *
+ * <div class="alert alert-warning">
+ * **Note:** `ngModel` compares by reference, not value. This is important when binding to an
+ * array of objects. See an example {@link http://jsfiddle.net/qWzTb/ in this jsfiddle}.
+ * </div>
+ *
+ * Optionally, a single hard-coded `<option>` element, with the value set to an empty string, can
+ * be nested into the `<select>` element. This element will then represent the `null` or "not selected"
+ * option. See example below for demonstration.
+ *
+ * <div class="alert alert-warning">
+ * **Note:** `ngOptions` provides an iterator facility for the `<option>` element which should be used instead
+ * of {@link ng.directive:ngRepeat ngRepeat} when you want the
+ * `select` model to be bound to a non-string value. This is because an option element can only
+ * be bound to string values at present.
+ * </div>
+ *
+ * @param {string} ngModel Assignable angular expression to data-bind to.
+ * @param {string=} name Property name of the form under which the control is published.
+ * @param {string=} required The control is considered valid only if value is entered.
+ * @param {string=} ngRequired Adds `required` attribute and `required` validation constraint to
+ *    the element when the ngRequired expression evaluates to true. Use `ngRequired` instead of
+ *    `required` when you want to data-bind to the `required` attribute.
+ * @param {comprehension_expression=} ngOptions in one of the following forms:
+ *
+ *   * for array data sources:
+ *     * `label` **`for`** `value` **`in`** `array`
+ *     * `select` **`as`** `label` **`for`** `value` **`in`** `array`
+ *     * `label`  **`group by`** `group` **`for`** `value` **`in`** `array`
+ *     * `select` **`as`** `label` **`group by`** `group` **`for`** `value` **`in`** `array` **`track by`** `trackexpr`
+ *   * for object data sources:
+ *     * `label` **`for (`**`key` **`,`** `value`**`) in`** `object`
+ *     * `select` **`as`** `label` **`for (`**`key` **`,`** `value`**`) in`** `object`
+ *     * `label` **`group by`** `group` **`for (`**`key`**`,`** `value`**`) in`** `object`
+ *     * `select` **`as`** `label` **`group by`** `group`
+ *         **`for` `(`**`key`**`,`** `value`**`) in`** `object`
+ *
+ * Where:
+ *
+ *   * `array` / `object`: an expression which evaluates to an array / object to iterate over.
+ *   * `value`: local variable which will refer to each item in the `array` or each property value
+ *      of `object` during iteration.
+ *   * `key`: local variable which will refer to a property name in `object` during iteration.
+ *   * `label`: The result of this expression will be the label for `<option>` element. The
+ *     `expression` will most likely refer to the `value` variable (e.g. `value.propertyName`).
+ *   * `select`: The result of this expression will be bound to the model of the parent `<select>`
+ *      element. If not specified, `select` expression will default to `value`.
+ *   * `group`: The result of this expression will be used to group options using the `<optgroup>`
+ *      DOM element.
+ *   * `trackexpr`: Used when working with an array of objects. The result of this expression will be
+ *      used to identify the objects in the array. The `trackexpr` will most likely refer to the
+ *     `value` variable (e.g. `value.propertyName`).

+ * JSTestDriver adapter for angular scenario tests
+ *
+ * Example of jsTestDriver.conf for running scenario tests with JSTD:
+  <pre>
+    server: http://localhost:9877
+
+    load:
+      - lib/angular-scenario.js
+      - lib/jstd-scenario-adapter-config.js
+      - lib/jstd-scenario-adapter.js
+      # your test files go here #
+
+    proxy:
+     - {matcher: "/your-prefix/*", server: "http://localhost:8000/"}
+  </pre>
+ *
+ * For more information on how to configure jstd proxy, see {@link http://code.google.com/p/js-test-driver/wiki/Proxy}
+ * Note the order of files - it's important !
+ *
+ * Example of jstd-scenario-adapter-config.js
+  <pre>
+    var jstdScenarioAdapter = {
+      relativeUrlPrefix: '/your-prefix/'
+    };
+  </pre>
+ *
+ * Whenever you use <code>browser().navigateTo('relativeUrl')</code> in your scenario test, the relativeUrlPrefix will be prepended.
+ * You have to configure this to work together with JSTD proxy.
+ *
+ * Let's assume you are using the above configuration (jsTestDriver.conf and jstd-scenario-adapter-config.js):
+ * Now, when you call <code>browser().navigateTo('index.html')</code> in your scenario test, the browser will open /your-prefix/index.html.
+ * That matches the proxy, so JSTD will proxy this request to http://localhost:8000/index.html.
