Vect	Class of two-dimensional vectors.
Rect(top, right, bottom, left)	Holds the dimensions of a rectangle.

class boxes.cartesian.Vect(x, y)

Class of two-dimensional vectors.

This a named tuple (see collections.namedtuple() from the python standard library) with an x and a y attribute. Implements __add__() and __sub__().

class boxes.cartesian.Rect(top, right, bottom, left)

Holds the dimensions of a rectangle.

Objects of this class cannot be modified after creation

>>> from boxes.cartesian import Rect
>>> r = Rect(0, 1, 1, 0)
>>> r.right = 2
