> Currently it is cumbersome or not possible to return no or multiple records from match,
cross, reduce, and cogroup. 
> When implementing the triangle enumeration example, I found this to be the most difficult
part. 
> As many MR algorithms require this feature, I think we should have good support for these
usecases.
> On approach to enable this emitting an arbitrary number of records could be to "collect"
output records in Scala lists and emitting them at the end of the stub call.
