/**
* Iterates over a TupleStream and buffers Tuples that are equal based on a comparator.
* This allows tuples to be grouped by common field(s).
*
* The read() method emits one tuple per group. The fields of the emitted Tuple reflect the first tuple
* encountered in the group.
*
* Use the Tuple.getMaps() method to return all the Tuples in the group. This method returns
* a list of maps (including the group head), which hold the data for each Tuple in the group.
*
* Note: The ReducerStream requires that it's underlying stream be sorted and partitioned by the same
* fields as it's comparator.
*
* The HavingStream iterates over an internal stream and applies a BooleanOperation to each tuple. If the BooleanOperation
* evaluates to true then the HavingStream emits the tuple, if it returns false the tuple is not emitted.
