Description

  1. correct the behavior of the method for digraphs. Before, M[i, j] was either the distance from i to j or the distance from j to i. It is now the shortest path distance from i to j.
  2. add parameter vertices to specify the mapping vertices to consecutive integers
  3. allow to specify the parameters of method distance_all_pairs

it's -> its.

To get the correct links, you probably want :meth:`~sage.graphs.generic_graph.GenericGraph.foo` as GenericGraph is not imported into the global namespace; although since it within that class, I think you can just do :meth:`foo`.

LGTM otherwise and you can set a positive review once fixed.

Thanks for the review.

For the link, the form :meth:`foo` is working properly. I'm regularly building the html doc to check.
