Chris@16:     \details Box is always described by a min_corner() and a max_corner() point. If another
Chris@16:         rectangle is used, use linear_ring or polygon.
Chris@16:     \note Boxes are for selections and for calculating the envelope of geometries. Not all algorithms
Chris@16:     are implemented for box. Boxes are also used in Spatial Indexes.
Chris@16:     \tparam Point point type. The box takes a point type as template parameter.
Chris@16:     The point type can be any point type.
Chris@16:     It can be 2D but can also be 3D or more dimensional.
Chris@16:     The box can also take a latlong point type as template parameter.
