Detailed Description

Abstract implementation of a notification facility. Clients add EventListeners with addListener and remove them with removeListener. Notifiers call notifyChanged when they wish to notify listeners. This queues the listener list on the notification thread, which eventually dequeues the list and calls notifyListener on each listener in the list.

Subclasses override acceptsListener and notifyListener to add type-safe notification. AcceptsListener should return true if the listener is of the appropriate type; ICUNotifier itself will ensure the listener is non-null and that the identical listener is not already registered with the Notifier. NotifyListener should cast the listener to the appropriate type and call the appropriate method on the listener.
