Hello.

In the Boost Graph Library, I need to map between two separate graphs  
where the IDs for the nodes are identical. I am unsure how to do  
this. It seems the property maps only allow mapping from vertex and  
edge descriptors to properties. How do we invert this? That is, how  
can we map from properties to vertex descriptors? If I have a vertex  
descriptor in one graph, I can map it to the vertex name-property,  
but then I want to map the vertex-name property to a vertex  
descriptor for the other graph. Please help.

                Best wishes,
                Luqman
