return offset
Places an object at the coordinate ``cords`` in ``grid``,
        growing the grid and updating ``fringe``, if necessary.
        Returns (0, 0) if no row or column has been prepended, (1, 0)
        if a row was prepended, (0, 1) if a column was prepended and
        (1, 1) if both a column and a row were prepended.
Places an object at the coordinate ``cords`` in ``grid``,

        Returns (0, 0) if no row or column has been prepended, (1, 0)

Places an object at the coordinate cords in grid growing the grid and updating fringe if necessary . Returns ( 0 0 ) if no row or column has been prepended ( 1 0 ) if a row was prepended ( 0 1 ) if a column was prepended and ( 1 1 ) if both a column and a row were prepended .
