New description:
The RandomDirectedGNP generator is quit slow because it is written in
python. Also I propose to rewrite it in Cython.
With this ticket, I propose to create a file graph_generators_pyx.pyx
containing graphs and digraphs generators in cython and to provide a
faster implementation of the GNP generator for both graphs and digraphs.
