ChangeNotifierBuilder<T extends ChangeNotifier> class

A widget whose content stays synced with a ChangeNotifier. Given a notifier of a subclass of ChangeNotifier and a builder which builds widgets from properties of notifier, this class will automatically register itself as a listener of the ChangeNotifier and calls the builder method when the ChangeNotifier updates.
