/**
 * @ngdoc object
 * @name ngResource.$resource
 * @requires $http
 *
 * @description
 * A factory which creates a resource object that lets you interact with
 * [RESTful](http://en.wikipedia.org/wiki/Representational_State_Transfer) server-side data sources.
 *
 * The returned resource object has action methods which provide high-level behaviors without
 * the need to interact with the low level {@link ng.$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) {
 *    return $resource('/notes/:id', null,
 *        {
 *            '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 $scope
 *		app.controller('NotesCtrl', ['$scope', '$routeParams', 'Notes',
                                      function($scope, $routeParams, Notes) {
 *    // First get a note object from the factory
 *    var note = Notes.get({ id:$routeParams.id });
 *    $id = note.id;
 *
 *    // Now call update passing in the ID first then the object you are updating
 *    Notes.update({ id:$id }, note);
 *
 *    // This will PUT /notes/ID with the note object in the request payload
 *		}]);
 * </pre>
