      Description

      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.
