 * Created 1997 by Mario Weilguni <[e-mail]>. This file 
 * is ported from Mats Luthman's <[e-mail]> 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

// 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).
