\ingroup PkgSegmentDelaunayGraph2Ref

The class `Segment_Delaunay_graph_hierarchy_vertex_base_2` provides a model for the 
`SegmentDelaunayGraphHierarchyVertexBase_2` concept, which is the 
vertex base required by the 
`Segment_Delaunay_graph_hierarchy_2<Gt,DS>` class. 

\tparam Vbb must be a model of the `SegmentDelaunayGraphVertexBase_2` concept.
