public class AggrShifter extends AggregatorModule
This class handles those fields that need to be moved, or shifted, from one field id to another field id. This is done with a simple factor value which is added to the field id when shifting occurs. Shifting occurs conditionally, when a certain field matches the pre-configured value.
