-    The `NetworkActivityIndicatorManager` manages the state of the network activity indicator in the status bar. When

-    animating the indicator accordingly. The indicator will continue to animate while the internal activity count is
-    greater than zero.
-
-    To use the `NetworkActivityIndicatorManager`, the `sharedManager` should be enabled in the
-    `application:didFinishLaunchingWithOptions:` method in the `AppDelegate`. This can be done with the following:
-
-        NetworkActivityIndicatorManager.sharedManager.isEnabled = true
-
-    By setting the `isEnabled` property to `true` for the `sharedManager`, the network activity indicator will show and
-    hide automatically as Alamofire requests start and complete. You should not ever need to call
-    `incrementActivityCount` and `decrementActivityCount` yourself.
