- \note Boxes are for selections and for calculating the envelope of geometries. Not all algorithms
- are implemented for box. Boxes are also used in Spatial Indexes.
- \tparam Point point type. The box takes a point type as template parameter.
- The point type can be any point type.
- It can be 2D but can also be 3D or more dimensional.
