    <Description>
      <![CDATA[
      VoronoiDiagram2D is derived from Mesh, however it could not be used by VTKPolyDataWriter.
      We made the following changes:
      1. Changing typedef VoronoiDiagram2D::CellType from PolygonCell< CellInterfaceType > to Superclass::CellType
      2. Changing typedef VertexIterator from std::vector< PointType >::iterator to PointsContainerIterator
      3. Removal of typedef CellInterfaceType, which is the same as CellType
      4. Adding new typedef PolygonCellType as PolygonCell< CellType >
      Now we are able to write VoronoiDiagram2D as mesh using VTKPolyDataWriter.
