function cIm = hrCi2cIm(hrCi)
% HRCI2CIM Transforms a 2D high-res (24 bits) classification image (hrCi)
%	into a uint8 color image (cIm). The color image can then be saved in 
% 	your favorite image format without loss of information (e.g., TIF). 
% 	E.g.,	Ci = rand(256,256);
% 			hrCi = round((256^3 - 1) * Ci);
% 			cIm = hrCi2cIm(hrCi);
