0020 \brief Traits class to create an object of Geometry type.
0021 \details This trait is optional and allows to define efficient way of creating Geometries.
0022 \ingroup traits
0023 \par Geometries:
0024     - points
0025     - boxes
0026     - segments
0027 \par Specializations should provide:
0028     - static const bool is_specialized = true;
0029     - static member function apply() taking:
0030       - N coordinates (points)
0031       - 2 points, min and max (boxes)
0032       - 2 points, first and second (segments)
