      Description copied from class: InternalAggregation
      Reduces the given aggregations to a single one and returns it. In most cases, the assumption will be the all given aggregations are of the same type (the same type as this aggregation). For best efficiency, when implementing, try reusing an existing instance (typically the first in the given list) to save on redundant object construction.
