Originally this tool used the colorconversion library by smcc but as it is no longer available from that site, I've included it in this release.

Changes

0.4 images with high contrast might gave incorrect values, fixed
0.3 optimized for speed, made a couple of parameters configurable
0.2 included the colorconversion library in the tarball
0.1 initial release
