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