[computer-go] C++: #include vs .h files

[Peter Drake]

That mostly worked, but I have a more subtle problem.

I have two classes, BitBoard and BoardState. Each needs to know about  
the other because the other appears in field declarations or method  
signatures. If I put

#include "BoardState.h"

in BitBoard.h and vice versa, there is obviously a circularity. How  
to get around this?
