// \brief Compute the minimal oriented bounding box for several 3D shapes
// \author Peter Vanroose
// \date   16 October 2009
//
// Given a 3D geometric object like a set of points, an ellipsoid, ...
// find the bounding box with the minimal volume that completely contains
// the given object. "Bounding box" is defined here as a Euclidean box
// (with mutually orthogonal rectangular faces), i.e., a vgl_orient_box_3d<T>.
//
// The class vgl_orient_box_3d_operators is actually a kind of namespace:
// it is just a collection of static methods, all returning a minimal box.
