HelpModelEvent and
HelpModelListener support changes to the
locations within HelpSets being presented,
TextHelpModelEvent and
TextHelpModelListener support textual changes
and HelpSetEvent, and
HelpSetListener support changes to the HelpSet
itself.
EventListenerList is used as a convenience
class to maintain lists of listeners and it is functionally
equivalent to the equivalent Swing class--it is included to
avoid adding unwanted dependencies on Swing.
