Rock Paper Scissor

This program plays rock paper scissors by trying to predict your next move. It will improve as more games are played.

Note: this program remembers the your last 3 moves and plays based on what you were most likely to choose after those 3 moves came up in the past. This allows it to beat all simple strategies (if you did x last time, then do y this time) and perform decently against "random" human-generated decisions. To prove that it isn't cheating, the program shows you the hash of its prediction along with a random number. That way, you can make sure it didn't change its move without being able to determine what that move is.
