* @workInProgress

* @ngdoc service

* @name angular.service.$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 overriden, removed or mocked for testing.

*

* All expressions are evaluated with respect to current scope so they don't

* suffer from window globality.

*

* @example

<input ng:init="$window = $service('$window'); greeting='Hello World!'" type="text" name="greeting" />

<button ng:click="$window.alert(greeting)">ALERT</button>
