7455	vertex_property should inherit publicly from vertex_property_type	sjackman@…	Jeremiah Willcock	"Hi,

vertex_property and edge_property should inherit publicly from
vertex_property_type and edge_property_type. A patch follows.

{{{
./ContigGraph.h:55:39: error: 'type' is a private member of
      'boost::mpl::eval_if<boost::detail::has_vertex_property_type<DirectedGraph<ContigProperties,
      Distance>, mpl_::bool_<false>>,
      boost::detail::get_vertex_property_type<DirectedGraph<ContigProperties,
      Distance>>, boost::no_property>'
        typedef typename vertex_property<G>::type vertex_property_type;
                                             ^
/usr/local/include/boost/graph/properties.hpp:251:49: note: constrained by
      implicitly private inheritance here
  template <class Graph> class vertex_property: vertex_property_type<Graph> {};
                                                ^~~~~~~~~~~~~~~~~~~~~~~~~~~
}}}

Cheers,
Shaun
