-This shares many similarities with the 2D-v2 code (ie. AI uses minimax algorithm to make decisions.)
-Differences include the use of SVG for the graphics drawing, "pruning" of the minmax tree, and touch swipe functionality for the mobile device.
-Used a more efficient checkWin() function saving an order of magnitude in AI decision time.
-Used alpha-beta pruning on minmax tree, allowing AI to shift depth cutoff from 1 to 4 and equal decision time.
