Changed a bit to the Bend class. Can now move bends back again
The moveBendBack function works on all bends at the same time.Other little additions for convinience
Added overloads of all setPeg functions to take Coords. Began reimplementation of snake output code
The board can now safely move snake in straight direction.
Accidentally got back to the same way of storing bends and I had begun with, but moved all that to a class.
Fixed an operator overload in Coord
Can sort of, somewhat, maybe handle bends...
