SEE test suite for Xiangqi (Chinese chess)

[phhnguyen]

I have just created a new test suite for testing Static Exchange Evaluation (SEE) for Xiangqi (Chinese chess).
- It is in EPD format: bm (bestmove) is actually the move to test and ce is the gaining score in centipawn
- Piece values: Rook: 1000, Cannon: 500, Horse: 400, Elephant: 200, Advisor: 200, Pawn: 200
- The test considers that a King can capture the other King (it is not obvious as standard chess)

Is it wise to have different value for Cannon and Horse? Late in the game the Horse is worth more than a Cannon. In Chess we also count B=N in SEE, even though usually B > N (e.g. because of the Bishop pair). It seems more natural to have R=8, C=H=4, A=E=passed P=2, unpassed P=1.

You are totally right! Thanks!
