/*
	
	Created 3/26/96 - Tim Craycroft

	
	A subclass of LTableSelector that always selects entire rows.
	Supports multiple selection and std selection extension semantics.
	
	Kind of lame implementation.  We store an array (LArray) 
	of bytes, each byte representing a row.  Easier than expanding
	and collapsing an array of bits.
