Hi!
I pushed some changes. @vasia told me that she and @StephanEwen even
decided that iterating on triplets is unfeasible, so we should operate on
`<srcVertex, edge>` pairs instead. Only a few changes were required, since
neither of the examples require the target vertex value anyway.
Regarding the other suggestions, @vasia and I think it would be a good idea
to push them in a separate PR, because they affect both GSA and Vertex centric
iterations.
Regarding the cosmetic changes that @andralungu suggested: I changed SSSP
to use `SingleSourceShortestPathData`, and for greedy graph coloring I just
generated a graph, like in `LabelPropagationExample`.
Cheers!
