+ * This function creates a mock window object useful for controlling access ot setTimeout, but mocking out
+ * sufficient window's properties to allow Angular to execute.
+ *
+ * @example
+ *
+ * <pre>

+      $provide.value('$window', window = angular.mock.createMockWindow());

+      $window.setTimeout(function() { val = 123; }, 10);
+      expect(val).toEqual(null);
+      window.setTimeout.expect(10).process();
+      expect(val).toEqual(123);
+    });
