> This will be a method that implements the GAS computation model, but without
> the "scatter" step. The phases can be mapped into the following steps inside
> a delta iteration:
> gather: a map on each < srcVertex, edge, trgVertex > that produces a partial
> value
> sum: a reduce that combines the partial values
> apply: join with vertex set to update the vertex values using the results of
> sum and the previous state.
