1.  abstract class AggregationWithDeaggBase extends AggregationSpec

   Base class for aggregation functions that support the deagg operation (e.g.

   Base class for aggregation functions that support the deagg operation (e.g. Sum/Avg). This class provides common functionality to keep track of a running count aggregation while performing the implemented aggregation type. Keeping track of the running count is important in order to identify when all records have been deagged out so the aggregate value can be properly reset. This is important to maintain current expectation where aggregate value is null when there are no records to aggregate together and to prevent floating point rounding errors causing the deagged aggregate value to be infinitesimally small instead of equal to zero. This class abstracts way the management of the count aggregation column so child classes only have to worry about implementing the aggregation function for the value column.
