This commit gets creates the ObjectOriented scene and gets it working. The current test program swaps a triangle from small to large with the 1 and 2 keys on the keyboard. (1 for small and 2 for large). The small triangle is rendered by the simple scene and the large one is rendered by the object oriented one.
