Incorporated Slick2D (which uses LWJGL) to manage the graphical aspect
of the game. Started completing the render method, where the graphical
interpretation of the smallBoards will take place. 

Next: 
-continue with render method, adding code to render the symbols of an
individual grid
-add main Board functions to change when smallBoards are won
-mouseListener and finding the location of clicks
-adding Slick2D and LWJGL to local lib folder so they are included in
commits
