2008-07-03 Lots of reworking. Completed support for game history, including Turn class. Changed Game API around quite a bit.
2008-03-07 Initial check-in into Mercurial. Branched from 1.0 release of Apple's sample code. No longer requires garbage collection. Fixed some memory leaks of CG objects. Fixed a bug when advancing to the 8th row in the Checkers game.
