Made the computer player smart. Only cats games.

What I changed
Updated the LookaheadStrategy for the computer player

Why I changed it
In this case, we weren't asked to develop the strategy (thankfully!)
but instead just tasked with pointing the computer player class to
using that strategy instead of making a random choice.

Estimate for remaining time to finish assignment: [Time for Nim?]
