Hello,

I have a problem trying to use a Vertex_handle: I want to navigate the 
vertices of a polyhedron so I use a Halfedge_handle and I keep a std::map of 
every vertex I visit, e.g.

std::map<Polyhedron::Vertex_handle, double> mymap;

Something like

Halfedge_handle = mypolyhedron.halfedges_begin();
mymap.insert(make_pair(h->vertex(), 0.0);
h = h->next();
mymap.insert(make_pair(h->vertex(), 1.0);
etc. 

The problem seems to be, the temporary Vertex_handle in the above appears to 
be the same object; the map won't insert the second vertex because it thinks 
it is the same as the first.

Please can someone explain how to use a Vertex_handle in this kind of 
situation and secondly, can you point me to where I can find the definition 
of Vertex_handle and Halfedge_handle.

Many thanks

Lyndon Hill
