public interface INotifier
An entity that a number of listeners can be registered with and that can fire events to these registered listeners.

Implementors are encouraged to document the event types that they are able to fire and that their listeners may want to receive and handle.

Implementors may want to extend Notifier instead of implementing this interface directly.
