x1) an enum called Shape with all possible shapes
x2) an enum called Colour with all (two) possible colours
x3) a struct called Piece that has a Shape and a Colour
x4) a dictionary storing the 64 squares of the chessboard. Each square has either a Piece 	or nil. Use an optional type for the values and that position(column row) function 	for the keys
x5) a dictionary representing the initial configuration of a board
/6) a dictionary representing this configuration:
