/**
 * @ngdoc object
 * @name ng.$window
 *
 * @description
 * A reference to the browser's `window` object. While `window`
 * is globally available in JavaScript, it causes testability problems, because
 * it is a global variable. In angular we always refer to it through the
 * `$window` service, so it may be overridden, removed or mocked for testing.
 *
 * All expressions are evaluated with respect to current scope so they don't
 * suffer from window globality.
 *
 * @example
   <doc:example>
     <doc:source>
       <script>
         function Ctrl($scope, $window) {
           $scope.$window = $window;
           $scope.greeting = 'Hello, World!';
         }
       </script>
       <div ng-controller="Ctrl">
         <input type="text" ng-model="greeting" />
         <button ng-click="$window.alert(greeting)">ALERT</button>
       </div>
     </doc:source>
     <doc:scenario>
      it('should display the greeting in the input box', function() {
       input('greeting').enter('Hello, E2E Tests');
       // If we click the button it will block the test runner
       // element(':button').click();
      });
