The calling convention for it within matlab is output = handeval(my_hand, board, cards_to_put_out, opponent_vector)
- my_hand is the pocket hand I am holding in a transformed integer description
- board is the current board,  means there is no board currently
- cards_to_put_out is the number of cards I want to put out to see my strength, say I'm on the flop and want to know how strong I am on the river, then the board is 3 cards and to_put_out is 2
- opponent_vector is optional, it's a distribution of length C(52,2) of what pocket I believe the opponent has. If no distribution is supplied the uniform is assumed.
