Initial Update

This update defines two gamestates, GameStatePart1 and GameStatePart2
that are called upon in the class SwapBetweenGamestates. Uploading in a
SubBranch just to see what happens.
part2+part2
Working example of State swapping

Run SwapBetweenGamestates and use "A" and "S" to swap between the
states. Uses old photo of me to visually show GameStatePart1 and a black
screen to show GameStatePart2.
