A simple bounding box. Operations on bounding boxes are designed to be fast, not accurate. The only guarantee on any bounding box operation is that objects reported to be outside a bounding box, are.
A convenience class for any finite geometry. In particular, it's easy to concatenate the bounding box of multiple geometries by placing them in a list and taking the bounding box of the entire list.
