You are welcome to take a look at my classes.  They uses 8 bit table
lookups for just about everything.  I imagine that the code can be
improved since my program is only half as fast as crafty.  Still, the
classes encapsulate the complexity nicely.

Sorry about the lack of comments in the code.
Suggestions for how to impove the code are welcome.  I am new to chess
programming.
