@vasia should `Graph` be using the function specific
`TypeExtractor.getMapReturnTypes` (not sure why this is plural) and similar
where core Functions are used?
For `Gelly` functions, I think you are right that this capability is
lacking, i.e. `NeighborsFunctionWithVertexValue` has three input types and
`TypeExtractor` only provides `getUnaryOperatorReturnType` and
`getBinaryOperatorReturnType`? It also looks like `TypeExtractor` expects a
specific though natural ordering (input types before output types).
@twalthr what do you recommend?
