@greghogan @vasia I've update the code according to your suggestion.
The only thing that I did differently: I return Tuple4 from a more complete
version of a bottom/top projections it contains vertex key, vertex value and
values of two vertices. I assumed that to get values of two other vertices I
would need to perform two other joins which will make the method much slower,
while a user can do with the result of the method if needed.
> Add Bipartite Graph Support for Gelly

>
> A bipartite graph is a graph for which the set of vertices can be divided
> into two disjoint sets such that each edge having a source vertex in the
> first set, will have a target vertex in the second set. We would like to
> support efficient operations for this type of graphs along with a set of
> metrics(http://jponnela.com/web_documents/twomode.pdf).
