        Initialize on the given sequence -- may take lists, tuples, NumPy arrays
        of X,Y pairs, or Point objects.  If Point objects are used, ownership is
        _not_ transferred to the LineString object.

        Examples:
         ls = LineString((1, 1), (2, 2))
         ls = LineString([(1, 1), (2, 2)])
         ls = LineString(array([(1, 1), (2, 2)]))
         ls = LineString(Point(1, 1), Point(2, 2))
