Given a line defined by (x1,y1) & (x2,y2),return the number of squares that the line crosses on the grid (a square is 1x1).
Coming next: return the number of squares for any geometrical shape
Bug: The order of the arguments in the starting function definition is x1, x2, y1, y2, whereas the the order in the test cases is x1, y1, x2, y2.
