Improve mention of aggregate() in the partitionAggregate() docs It was not obvious (to me) that aggregate() is covered in detail at another place in the document. That specific section describes the details of the optimization much more exhaustively. Also, it was unclear what the benefits should be compared to, because other aggregator types are only introduced afterwards.

In that case, Trident automatically optimizes the computation by doing partial aggregations before transferring tuples over the network. +CombinerAggregators offer high efficiency when used with the aggregate method instead of partitionAggregate ([see below](#aggregation-operations)).
