  Not Golfed? I don't recognize that term. I don't see the python 
source off hand, but I don't understand python anyways.

  I've managed to make a full solver in about 187 lines (4.5k) in 
the last hour (although lacking a few unittests); It does 2 
methods to attempt to solve it (Only possible option & brute 
force). Unoptimized it takes 82 seconds with the hardest supplied 
puzzle; But when optimized it goes down to 12 seconds.
