%	_____OUTPUTS____________________________________________________________
%	lhash	LANS hash structure				(struct)
%		.list	list of values in each dimension	(cell)
%		.idx	indices of values in each dimension	(cell)
%		.max	max # of elements in each cell dimension(cell)
%		.point	current hash pointer/index		(cell)
%			all initialized to 1
%		.read	current pointed values			(cell)
%
%		.amax	max # of elements (in all dimensions)	(scalar)

%	_____NOTES______________________________________________________________
%	- use mainly as a fault-recovery counter for lans_sim
%	- .cpoint faciliates indexing array access, i.e. .cpoint{:} as in
%	    sex(vhash.cpoint{:})=tex
%	   which cannot be done with sex(vhash.point)
%	   however
