 43    /** Keeps track of all listeners to an InteractionsModel, and has the ability to notify them of some event. <p>
 44    * This class has a specific role of managing InteractionsListeners. Other classes with similar names use similar
 45    * code to perform the same function for other interfaces, e.g. JavadocEventNotifier and GlobalEventNotifier.
 46    * These classes implement the appropriate interface definition so that they can be used transparently as composite
 47    * packaging for a particular listener interface. <p>
 48    * Components which might otherwise manage their own list of listeners use EventNotifiers instead to simplify their
 49    * internal implementation. Notifiers should therefore be considered a private implementation detail of the
 50    * components, and should not be used directly outside of the "host" component. <p>
 51    * All methods in this class must use the synchronization methods provided by ReaderWriterLock. This ensures
 52    * that multiple notifications (reads) can occur simultaneously, but only one thread can be adding or removing
 53    * listeners (writing) at a time, and no reads can occur during a write. <p>
 54    * <i>No</i> methods on this class should be synchronized using traditional Java synchronization! <p>
