I'm dealing with the same problem but I didn't get the methond Andreas has 
proposed. What's the thing about checking in a set<Vertex_handle>? So far 
I've managed to retrieve the incident cells but I'm wondering how I can visit 
the edges. the vertex v is fixed but how can I determine the other vertices? 
I understood that I can get the edges providing the indices of the vertices 
(0,1,2,3) how can I get these indices from a vertex handle?

Thanks for your help
