%  StripThickness -- measure the thickness of a strip containing all data
% 	Usage
% 		[thick,dirpair] = StripThickness(W,ns,nvert)
% 	Inputs
% 		W	part of Wedgelet transform associated to
% 			a dyadic square
% 		ns	number of vertices per side of square
% 		nvert	number of vertices per square
% 		         nvert = 4 * ns
% 	Outputs
% 		thick	thickness in pixels of strip containing all data
% 		dirpair	pair (i,k) defining two wedges containing all data
% 	See Also
% 		BetaPyramid
% 	Purpose
% 		This is an engine for BetaPyramid. Used in the
% 		analysis of 0/1 data.
% 		Helps to construct pyramid of thickness of data occupying dyadic squares
% 		measures thickness in units of ``quasi-pixels'', a measure within
% 		about 50 accurate of the true width of the minimal strip
