  //! Creates an array of polygons, a polygon can be filled as:
  //! 1) Creating a single polygon defined with his vertexes, i.e:
  //! @code
  //!   myArray = Graphic3d_ArrayOfPolygons (7);
  //!   myArray->AddVertex (x1, y1, z1);
  //!   ....
  //!   myArray->AddVertex (x7, y7, z7);
  //! @endcode
  //! 2) Creating separate polygons defined with a predefined number of bounds and the number of vertex per bound, i.e:
  //! @code
  //!   myArray = Graphic3d_ArrayOfPolygons (7, 2);
  //!   myArray->AddBound (4);
  //!   myArray->AddVertex (x1, y1, z1);

  //!   ....
