updated level class to support functionality, added canMove method
refactored CanMove to IsWall. Method takes a column and a row and a direction. It returns a boolean of whether a wall is in that direction. Further modified Level class so GridSize is an actual array.. Not sure how this will be used at this stage but a level can be initialized by changing this whereas before it couldn't.
Added some code to the Theseus.Move() and Minotaur.Move() functions.
consolidated Backend to Player. Level to follow monday
