This is just a personal annoyance and I think we are to advanced to change this now, but here goes: Could we rename the classes in the API, so that for example MapOperator becomes MapDataSet or MapSet, and the actual operators in the common package become MapOperator instead of MapOperatorBase.
My thinking is that two things called MapOperator are very confusing. If we want to change this we should do it fast. Cheers, Aljoscha
