/**
 * @ngdoc service
 * @name $componentController
 * @description
 * A service that can be used to create instances of component controllers.
 * <div class="alert alert-info">
 * Be aware that the controller will be instantiated and attached to the scope as specified in
 * the component definition object. If you do not provide a `$scope` object in the `locals` param
 * then the helper will create a new isolated scope as a child of `$rootScope`.
 * </div>
 * @param {string} componentName the name of the component whose controller we want to instantiate
 * @param {Object} locals Injection locals for Controller.
 * @param {Object=} bindings Properties to add to the controller before invoking the constructor. This is used
 *                           to simulate the `bindToController` feature and simplify certain kinds of tests.
 * @param {string=} ident Override the property name to use when attaching the controller to the scope.
 * @return {Object} Instance of requested controller.
