## To start a graphical game type:
##   start_graphical_othello_game(othello_player("Bob"), othello_player("Fred"))
## where othello_player can be replaced by MyPlayer or whatever you choose to
## call your class.

## To start a textual game (where you can have different AI players) type:
##  play_othello() will just start a default game,
##  play_othello(Othello(), 1800, MyPlayer("Name"), othello_player("Othername"))
## where MyPlayer is your class (which can have whatever name you want)
## and othello_player is just the dumb default.  You can have BobPlayer play
## FredPlayer if you define those two classes, for example.
