[Boost-users] Creating a copy of a subset of a graph

Hi All,

I want to form a new graph B from an existing graph A, copying out only 
edges(and their all their vertices) given that an edge contains at least 
one of the vertices in a given list (i.e. I am going to end up with a 
graph with more than just the vertices in the list and their adjacency 
information. With some extra vertices, where an edge exists between them 
and vertices in the defined list.)

I know I should be using filter_graph and copy_graph, but not 100% sure 
how. Any help/code snippets would be much appreciated, I am new to boost 
graph library so please make any explanations as simple as possible,

Adam
