case class MultiAggregatorMap[-A, B, +C](aggregatorsMap: List[(String, Aggregator[A, B, C])]) extends Aggregator[A, List[B], Map[String, C]] with Product with Serializable

Aggregator which combines an unbounded list of other aggregators. Each aggregator in the list is tagged by a string. The string(aka name) could be used to retrieve the aggregated value from the Map emitted by the "present" function.
