> We have completed codeGen for all aggregate runtime functions. Now we can
> finalize the AggregateFunction. This includes 1) remove Accumulator trait; 2)
> remove accumulate, retract, merge, resetAccumulator, getAccumulatorType
> methods from interface, and allow them as contracted methods for UDAGG; 3)
> refactoring the built-in aggregates accordingly.
