Regarding the rest of the comments:
- shall we change the SumFunction, ApplyFunction, etc. to have 2 versions,
i.e. single-abstract-interface and rich? If yes, it should be a good idea to go
the same for vertex-centric.
- the run/create slit is indeed for configuration, aggregators and
broadcast sets. We did the same for vertex-centric in #402. I do like your api
proposal more though, I guess we should change both :)
