//! Describes a bounding box in 3D space.
//! A bounding box is parallel to the axes of the coordinates
//! system. If it is finite, it is defined by the three intervals:
//! -   [ Xmin,Xmax ],
//! -   [ Ymin,Ymax ],
//! -   [ Zmin,Zmax ].
//! A bounding box may be infinite (i.e. open) in one or more
//! directions. It is said to be:
//! -   OpenXmin if it is infinite on the negative side of the   "X Direction";
//! -   OpenXmax if it is infinite on the positive side of the "X Direction";
//! -   OpenYmin if it is infinite on the negative side of the   "Y Direction";
//! -   OpenYmax if it is infinite on the positive side of the "Y Direction";
//! -   OpenZmin if it is infinite on the negative side of the   "Z Direction";
//! -   OpenZmax if it is infinite on the positive side of the "Z Direction";
//! -   WholeSpace if it is infinite in all six directions. In this
//! case, any point of the space is inside the box;
//! -   Void if it is empty. In this case, there is no point included in the box.
//! A bounding box is defined by:
//! -   six bounds (Xmin, Xmax, Ymin, Ymax, Zmin and
//! Zmax) which limit the bounding box if it is finite,
//! -   eight flags (OpenXmin, OpenXmax, OpenYmin,
//! OpenYmax, OpenZmin, OpenZmax,
//! WholeSpace and Void) which describe the
//! bounding box if it is infinite or empty, and
//! -   a gap, which is included on both sides in any direction
//! when consulting the finite bounds of the box.
