The following two methods are the most crucial to the game. Study them and
make sure you understand how they work.

ASSIGNMENT:
Do the following:
- Make a flashier ending (something using TimerTask to do a little
animated production).
- Make TWOs wild so that they are automatically multiplied with highest
card(s) dealt.
