* Provides a directive that resizes the map in an animation loop

* of the map size.
*
* Example:
*
* <div ng-class="ctrl.open ? 'open' : 'close' ngeo-resizemap="ctrl.map"
* ngeo-resizemap-state="open">
* <div>
* <input type="checkbox" ng-model="ctrl.open" />
*
* See our live example: [../examples/animation.html](../examples/animation.html)
*
* @param {angular.IWindowService} $window Angular window service.
* @return {angular.IDirective} The directive specs.
* @ngInject
