Hello, I have a problem with adjacency_matrix template. It claims to implement VertexAndEdgeListGraphConcept, BidirectionalGraphConcept and MutablePropertyGraphConcept. But when I try to compile, it complains about using the next functions with an adjacency_matrix: num_vertices(graph) vertices(graph) num_edges(graph) edges(graph) source(edge_descriptor, graph) target(edge_descriptor, graph) and also with get(&V::property, graph), where V is a vetex bundled-properties type get(&E::property, graph), where E is an edge bundled-properties type (these get functions should return a property map for the corresponding bundled property and they work correctly for adjacency_list, just like the rest). Is this a bug or an error in the documentation? Thanks a lot, Juan
