        Box

is a 2D box.

The can be constructed either with two tuples, giving two points delimiting the box, or with four arguments x0, x1, y0, y1.

To access the thing, you can either access the x[01], y[01] attributes or use getitem to retrieve the upper right and lower left corner.

The slightly silly ordering of the bounding points (larger values first) is for consistency with Postgresql.
