* A Reversi (or sometimes called Othello) game

*
* Created 1997 by Mario Weilguni <mweilguni@sime.com>. This file
* is ported from Mats Luthman's <Mats.Luthman@sylog.se> JAVA applet.
* Many thanks to Mr. Luthman who has allowed me to put this port
* under the GNU GPL. Without his wonderful game engine kreversi
* would be just another of those Reversi programs a five year old
* child could beat easily. But with it it's a worthy opponent!
*
* If you are interested on the JAVA applet of Mr. Luthman take a
* look at http://www.sylog.se/~mats/

// The class Game represents a complete or incomplete Othello game. It uses
// the classes Score and Move (and internally Position).
// You can make moves, take back one move at a time, reset to initial position
// and get certain data on the current position.
// Public functions:
// public Game()
// Creates a game with the initial position.
// public void Reset()
// Resets to the initial position.
// public boolean MakeMove(Move m)
// Makes the move m. Returns false if the move is not legal or when called
// with a move where the player is Score.NOBODY.
// public boolean TakeBackMove()
// Takes back a move. Returns true if not at the initial position.
// public int GetSquare(int x, int y)
// Returns the piece at (x, y). Returns Score.NOBODY if the square is not
// occupied.
// public int GetScore(int player)
// Returns the score for player.
// public Move GetLastMove()
// Returns the last move. Returns null if at the initial position.
// public boolean MoveIsLegal(Move m)
// Checks if move m is legal.
// public boolean MoveIsPossible(int player)
// Checks if there is a legal move for player.
// public boolean MoveIsAtAllPossible()
// Checks if there are any legal moves at all.
// public int GetMoveNumber()
// Returns move number.
// public int GetWhoseTurn()
// Returns the player in turn to play (if there are no legal moves
// Score.NOBODY is returned).
// public Move[] TurnedByLastMove()
// Returns a vector of the squares that were changed by the last move.
// The move that was actually played is at index 0. At the initial
// position the length of the vector returned is zero. (Could be used
// for faster updates of a graphical board).
