How to handle the 0-edge case ?

The modularity metric formula would divide by 0 since M = 0 when the graph size equals the same.
It would be 'natural' to return a set of singletons with Louvain but since it is based on maximizing the modularity metric, it should also be consistent with the latter's considerations.

Currently, both Louvain and Modularity modules throw.
