public class ExpandableList
Subclass of JList intended to grow as elements are added to the list (via the model, but that's not seen by clients). Features added to this JList not part of standard JList
the default JList supports ListSelectionListeners, this class adds ActionListeners via double-clicking, selected items are converted to strings via toString()
