Decided to subclass UIScrollView for the chessboard to allow users to scroll when they play. GameManager will act as a liaison between the tile and player model controllers. GameManager’s the view controller for chessboard and will be responsible for any animations i do later. GameScreenController will manage all other UIViews and sometimes ChessboardView.

Documentation of relationship between classes will be added in the next couple of commits.
Improved directory and added images to repository. Chess tile views can now be selected and deselected one at a time. Changed chess tile models so that tile state’s API will be interfaced using a string.
