InputManaager should not have specific move commands bound to keys
 - should have bindKey(Key, Command) method
 - should store map of {Key, Command} KeyPressed, SpecificCommand

Physics body for attaching to Snake

7/24/2018
Correctly rendered Snake head in both coordinates of SFML and Box2D

Created Collectible class, determined it should exist in the GameWorld
Command should return a moveState
physicsWorld.checkCollision(player, moveState);
TODO: Read type inheritance because Collectible is identical to SnakeSegment
I think I could get rid of SnakeSegment and Collectible and use GameActor
