    Does auto-boxing not work here?

> 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).
