+// 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).
