  20 \brief Traits class to create an object of Geometry type.
  21 \details This trait is optional and allows to define efficient way of creating Geometries.
  22 \ingroup traits
  23 \par Geometries:
  24     - points
  25     - boxes
  26     - segments
  27 \par Specializations should provide:
  28     - static const bool is_specialized = true;
  29     - static member function apply() taking:
  30       - N coordinates (points)
  31       - 2 points, min and max (boxes)
  32       - 2 points, first and second (segments)
