Message:

Extracted extraction (subset of) nodes from BoostGraph into BreadthFirstSearchGatherer.

• also added helper namespace BoostGraphHelpers.
• we now treat the vertex indices and vertex names properly. Before that they had to coincide. Now, the name is the atomic id associated with the node and the index is the boost::graph internal index.
