%  hvprimitive -- calculate `vertical and horizontal primitives'
% 	Usage
% 		[vprim,hprim] = hvprimitive(img)
% 	Inputs
% 		img		array n by m
% 	Outputs
% 		vprim	array n+1 by m, containing vert cum sums
% 		hprim	array n by m+1, containing horiz cum sums
% 	Description
% 		vprim(i,j) = sum_{u < i} img(u,j)
% 		hprim(i,j) = sum+{u < j} img(i,u)
% 	Notice
% 		vprim(1,j) == 0
% 		hprim(i,1) == 0
% 		vprim(n+1,j) = sum( img(:,j))
% 		hprim(i,m+1) = sum( img(i,:))
