class CoGroupedIterator extends Iterator[(InternalRow, Iterator[InternalRow], Iterator[InternalRow])]

Iterates over GroupedIterators and returns the cogrouped data, i.e. each record is a grouping key with its associated values from all GroupedIterators. Note: we assume the output of each GroupedIterator is ordered by the grouping key.
