Summary: LEDA graph adaptors do not handle hidden nodes properly

Initial Comment:
Hidden nodes are completely ignored by the LEDA graph adaptors.
This may cause problems when, for instance, there are hidden
nodes but the equivalent of vertex_index is used to construct a
(BGL) property map. The LEDA adaptors should probably take the
same approach as filtered_graph: let num_vertices() return the
number of the nodes in the graph plus the number of hidden nodes,
but vertices() filters out the hidden nodes. Similarly for edges.
