public class Game

extends GameState

This class represents a single game of chess.
It comprises the board, which is the location of the pieces;
the game, containing all other information about the game, like castling, ep, 50 move rule, etc.
and a single instance of Move that can be used by Pieces, for example, when iterating.

Using this single instance of Move makes iterating over all moves VERY efficient but VERY
non-thread safe. If you need a new Move, make it yourself!
