[boost] BUG: graphviz_write (boost_1_31_0)

        The graphviz_write function is inconsistent in how it writes
vertices.  When it write the vertex itself, it uses get(vertex_index,
...), but when it writes the edges, it just writes the vertex
descriptor.  When using adjacency_list< listS, listS,
bidirectionalS,... >, this produces bad output (the edges list their
endpoints by hexadecimal address values).

        Here's a patch:

      typename graph_traits<Graph>::edge_iterator ei, edge_end;
      for(tie(ei, edge_end) = edges(g); ei != edge_end; ++ei) {
!       out << source(*ei, g) << Traits::delimiter() << target(*ei, g) << " ";
        epw(out, *ei); //print edge attributes
        out << ";" << std::endl;
      }

      typename graph_traits<Graph>::edge_iterator ei, edge_end;
      for(tie(ei, edge_end) = edges(g); ei != edge_end; ++ei) {
!       out << get(vertex_index, source(*ei, g)) << Traits::delimiter() << get(vertex_index, target(*ei, g)) << " ";
        epw(out, *ei); //print edge attributes
        out << ";" << std::endl;
      }
