New description:
The function strongly_connected_components uses Networkx for the moment.
As c_graphs are to become the standard implementation of graphs in Sage,
this function should be rewritten in Cython.
This functions should be able to return two types of data :
* A list of lists : as the function connected_components
* A digraph whose vertices are [immutable Sets representing a set of
vertices defining a strongly connected components] and such that there is
an edge between A and B if there is an arc from one vertex of A to one
vertex of B.
This because, the graph strongly connected components is acyclic, which is
sometimes useful.
