Battle Checkers 1.11

Battle Checkers is an implementation of Checkers and Tower Checkers games. The rules of Checkers are well-known, so it is enough to say that this program uses Russian variant of rules (all checkers can eat backwards, king checker can move to any cell count along any diagonal.) Tower Checkers is formally defined as "the game in which the program plays", so the definition below is only for better understanding.
