Hi @andralungu!
Regarding (2), I think you could do that inside VertexCentricIteration
instead of inside a method of Graph.
Regarding (3), I agree that adding another VertexCentricIteration wouldn't
be a nice solution. Why don't you create the Tuple3 (or whatever you need based
on the options) vertex dataset inside `createResult()`? I don't see the need in
changing VertexCentricIteration's types / output.
