Sudoku solver

I had been working on a small sudoku solver.. Did not finish it though. It goes into infinite loops for difficult ones. You can check it here [ If my laptop is on - look at the status box at top right of my blog]. (Will upload to github when I Can)It is published under GPL license. My interest waned as I worked on it, people are most welcome on using it. At a rate of 1 to 10 for coding, I rate myself at 2.5 . So yeah, feel free to say my code sucks.

Please do anything with it under the GNU GPL.
