GUI: Write a class called RPSgui. This
will be a GUI to play a tournament of rock-paper-scissors.
Your GUI should allow the user to input a filename (or select a file from the current directory), have a button to start the tournament, have a button to repeat the tournament, and have a window that displays information about the tournament (stats after round robin, winner of tournament).
You can make modifications to the methods specifided in A10 (return types for example) if you wish.
