%ILABEL	Label an image
%
%		li = ILABEL(image)
%		[li,maxlabel] = ILABEL(image)
%
%	Perform connectivity analysis and return a label image LI, same size as 
%	IMAGE where each pixel value represents the label of the region of its
%	corresponding pixel in IMAGE.
%
%	Connectivity is performed using 4 nearest neighbour, and compares
%	the pixel values.  The image can be greyscale or binary.
%
%	Also returns the maximum label assigned to the image.  Labels lie in
%	the range 1 to MAXLABEL.
%
% SEE ALSO:	imoments
%
% LIMITATIONS:	should allow for different connectivity modes
