 Note: A "turn" is a single player's turn. A "round" is every player having one turn.
 Note: Since all variables are public in Python, it is trivial to have a bot that hacks the tournament code. Inspect the bot code before running it.
-Note: We don't use OOP for bots. A "zombie dice bot" simply implements a turn() method which calls a global roll() function as often as it likes. See documentation for details.
 
 Instructions for making your own bot can be found here: http://inventwithpython.com/blog/2012/11/21/how-to-make-ai-bots-for-zombie-dice
