+ * 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.</p>
+ *
+ * <p>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.
