Suggestion: replace Matrix{Bool} values with actual directed graphs from Graphs.jl.

Suggested in reaction to #76 because directed graphs is what is actually represented by most matrices in the package. Not sure what the cons and pros are here, except that it's not something worth bothering with yet, at least not before the next release. I'm just dropping it here for the records ;)

The big pro would be that we (developers) and the user could use directly algorithms from Graphs.jl, for instance to compute centrality metrics or search for communities.
I assume that the con is that we would be dependent of a structure that we didn't create, thus we don't have full control over it. But at this point, the trade-of seems very positive to me.

This change would be easier after #84 is addressed.

Closing in favour of #141.
