The Shell Game
Three (or more) cups. One has a ball underneath, and the rest are empty.
The person running the game will switch the cup positions over and over until they stop.
You, as the gambler, are trying to find which cup still has the ball.

Given the shell that the ball starts under, and a list of swaps, return the location of
the ball at the end.

For example, if my function name is find_the_ball, 
and the starting position is 0
and the swap sequence is [(0, 1), (1, 2), (1, 0)]
My function gets called as find_the_ball(0, [(0, 1), (1, 2), (1, 0)])
find_the_ball returns 2
