* 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/

// This file defines the two classes SimpleMove and Move.
//
// The class Move is used to represent an Othello move with a player value
// (see class Score) and a pair of coordinates on an 8x8 Othello board.
// Each coordinate can have values between 1 and 8, inclusive.
//
// The difference between a Move and a SimpleMove is that a SimpleMove
// can be done (performed) in a Position, but a Move can be both done
// and undone. In addition to the info in SimpleMove, the class Move
// stores information that is used in undoing the move and visualizing
// it.
//
// The reason for the class SimpleMove is that it saves memory. The
// class Game stores an array of Moves, since the BoardView needs
// information about which pieces were turned by the move.
//
