    Hi @vasia!
    I fixed the problems, sorry about that. I had to resolve some merge conflicts and it appears
that I did not notice some things. Next time I'll check the diff before I commit :)

> 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.
