23 Oct 2009	Divakar Roy	Added screenshot on here and images with their output images in the zipped file for all those people who are trying hard without actually knowing anything about how the contrast of images works, though I thought it is a straight-forward thing. Also added another version of contrast controller that works through another algorithm. Hope this helps out guys, cheers!
