Hotseat Connect 4 with Rotation

Our basic goal was to implement Connect 4 while allowing players to rotate the board after they place each token. We used JavaFX to create a GUI, after a series of misadventures in trying to use Swing, which culminated after several hours of work with our entire GUI being replaced by an octagonal face that was supposed to be one of our buttons. JavaFX, although intuitive, presented substantial substantial challenges due it its poor web integration, and we were unable to embed the app.
