Completed checkpoint 3

What I changed
(I gave the computer player the look ahead strategy. This also required importing LookaheadStrategy in player.py.
I also answered the questions in notes.md.)

Why I changed it
(I was working on completing checkpoint 3. I realized I had to do the importing since otherwise it wouldn't let me play.)

Estimate for remaining time to finish assignment: [I am REALLY bad at these estimates. I mean in terms of actual work time, I'm probably not too far off. Fingers crossed, maybe another hour of actual work time?]

 You can get the inital game state using game.get_initial_state().
