%      Description - The code is used to view the PNG format DDSM images
%                    created using the openDDSMLJPEG1AndConvertToPNG.m 
%                    script. This script opens the PNG file, and then also
%                    opens the corresponding OVERLAY file to get the boundary
%                    information of the mass present in that particular
