	//	Two subclasses of LBroadcaster and, respectively, LTableSingleSelector and LTableMultiSelector.
	//	Classes broadcasts a message every time table selection is about to change,
	//	and another message every time selection has changed. Messages are customizable.

	//	Useful if you have an LTableView and clicking in it causes entry data to be
	//	made available for the user to edit. When you receive mAboutToChangeMsg,
	//	you know it's time to retrieve the data shown and prepare to show another entry's data.

	//	cBroadcastingTableSelectors is free for any and all use. 
	//	Do not distribute modified source code under my name.
