 * Members and classes in the notification system include:
 * <p>
 * <ul>
 * <li>The {@link #listeners}member holds the list of subscribed listeners.
 * </li>
 * <li>The {@link #addListener}and {@link #removeListener}methods to add and

 * <li>The {@link Listener}class to receive notifications.</li>
 * <li>A subclass of {@link NotificationEvent}notifies the listener of the

 * {@link #broadcast(NotificationEvent)}to do the detailed work of sending an
 * event to all the listeners.</li>
