//
//	Basically, if you want to be the one to catch the leftover key events,
//	derive from this class and pass yourself to inputIFaceMgr.
//	(it'll auto-tell inputIFaceMgr when it goes away)
//
//	Note: if you want to do more than just get the darned key event (like
//	mouse events or key bindings or change the cursor or the like), don't do
//	this; create your own plInputInterface instead.
