Part #1: data

rock = 0, paper = 1, scissors = 2, quit = 3
score[3]: score[0] user, score[1] computer, score[2] ties


Part #2: functions
	-- get user input
	-- get computer choice
	-- determine winner

Part #3: main program algorithm:

score = [ 0, 0, 0 ]
while True:
	userchoice = getuser();
	if (userchoice == quit):
		break
	compchoice = getcomp();
	winner = whowins(userchoice, compchoice)
	score[winner] += 1;

print "You won", score[0], "games, the computer won", score[1],
print "games, and", score[2], "games were tied"
