Comment (by lkeough):
I'm not sure of the most relevant definition either, but
blocks_and_cut_vertices also uses the underlying graph for directed
graphs.
I tried using blocks and cut vertices to write is_cut_vertex, but it
appears to be much slower (as expected). I'm not sure of a better way to
implement this.
The tests all ran fine, maybe it's a good idea to add a digraphs
test/example?
