     *
     * @description
     * A root scope can be retrieved using the {@link ng.$rootScope $rootScope} key from the
     * {@link auto.$injector $injector}. Child scopes are created using the
     * {@link ng.$rootScope.Scope#$new $new()} method. (Most scopes are created automatically when
     * compiled HTML template is executed.)
     *
     * Here is a simple scope snippet to show how you can interact with the scope.
     * ```html
     * <file src="./test/ng/rootScopeSpec.js" tag="docs1" />
     * ```
     *
     * # Inheritance
     * A scope can inherit from a parent scope, as in this example:
     * ```js
         var parent = $rootScope;
         var child = parent.$new();

         parent.salutation = "Hello";
         child.name = "World";
         expect(child.salutation).toEqual('Hello');

         child.salutation = "Welcome";
         expect(child.salutation).toEqual('Welcome');
         expect(parent.salutation).toEqual('Hello');
     * ```
     *
     *
     * @param {Object.<string, function()>=} providers Map of service factory which need to be
     *                                       provided for the current scope. Defaults to {@link ng}.
     * @param {Object.<string, *>=} instanceCache Provides pre-instantiated services which should
     *                              append/override services provided by `providers`. This is handy
     *                              when unit-testing and having the need to override a default
     *                              service.
     * @returns {Object} Newly created scope.
