Major changes: - Based on Yingyi's review comments, the new interface is written to have the frame output logic out of the aggregators. - Added methods for better management of the size of aggregation states. Now aggregator developer can decide the memory size to be used, and the groupers will assign the memory/frame spaces based on these information. - Fixed some bugs in multiple-field aggregator.
