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))
