public class WolfsheepGame
extends AbstractGame

an implementation of the wolf&sheep game which is played on a chess-like board; it uses the BoardPosition from the chess package for convenience. The game is played with 1 'wolf' and 4 'sheeps'; the setup and rules are somewhat simillar to checker, but way simpler. Wolf and sheeps start on opposite sites of the board. The sheeps can only move forward diagonal; the wolf can move back&forth, but only diagonal, also. Hence, each sheep has 2 move option at most and the wolf has 4 move options at most. The sheeps' goal is to contain the wolf, so that it cannot move anymore. The wolf's goal is to bypass the sheeps closing line and reach the other side of the board. If the wolf moves first, the wolf represents game role 0 and the sheeps represent 1. If the sheeps move first, these game roles are reversed.
