Convinience module providing all bounding box functionallity in one place.
BBox1 type is basically a
Range, but all the operations over it work with
Vector1 (which is really
Scalar). While it's called a bounding box, a 1-dimensional box is in truth a simple line interval, just like
BBox2 is a 2D bounding box (aligned to the coordinate axies).
BBox3 is a 3D bounding box (aligned to the coordinate axies).
