Comment:
I need BFS to report the distance as well, the minimum number of
edges/arcs to be traversed for every vertex. The shortest_paths method
implements this, but it does not have any option to specify a neighbor
function, which is possible in the breadth_first_search method.
My commit is a small modification that does implement this.
