Changed the Bends to be a vector again because deque has problems with iterators. Made a function to be able to pop_front from a vector
Worked further on updateSnake function. Not as broken, but still far from complete
Added function to interact between directions and coordiantes (moved from Board)
Added arithmetic (+, -, +=, -=) operators to COORD class.
Moved the functions back to Board as they were causing *lots* of errors for no explicable reason
Changed the scope of some functions as they didn't belong in the class in the first place. Certain sections of the code are commented out to be changed later
minor update
Changed how bends are stored. Need to adjust some functions to reflect that change
