%	lans_cidx2class	- Recover class name from unique integer label
%
%	[cdata]	= lans_cidx2class(cidx,ctable)
%
%	_____OUTPUTS____________________________________________________________
%	cdata	data class labels			(cell/col vectors)
%
%	_____INPUTS_____________________________________________________________
%	cidx	converted class indices in integers	(row)
%	ctable	converstion lookup table		(cell)
%		(see lans_class2cidx)
%
%	_____EXAMPLE____________________________________________________________
%	[cidx,ctable]=lans_class2cidx({'A','B','A','A','B','B','C','B','C'});
%	cdata=lans_cidx2class(cidx,ctable)
%	[cidx,ctable]=lans_class2cidx({'5','3','4','2','10','B','C','B','C'});
%	cdata=lans_cidx2class(cidx,ctable)
%	[cidx,ctable]=lans_class2cidx([1 2 1 3;1 1 1 1]);
%	cdata=lans_cidx2class(cidx,ctable)
%	[cidx,ctable]=lans_class2cidx([5 2 2 3 5]);
%	cdata=lans_cidx2class(cidx,ctable)
%
%	_____NOTES______________________________________________________________
%	simple cell operations can be done via
%	cdata	= ctable(cidx)	!!!!!!!!!1
%	This function unifies cell and non-cell operations
%
