%cubs_enroll
%extracts the minutiae from a fingerprint image and writes them to the
%given template file
%syntax:
%cubs_enroll(image_file,template_file)
%image_file     = name of the image file (can be 8 bit tif or bmp)
%template_file  = name of the template file
%NOTE:
%The intermediate results are output in the files
% CUBSEnhanced.tif  - Enhanced Image
% CUBSBinary.tif    - Binarized Image
% CUBSContour_2.tif - Contour with potential minutiae highlighted
