Defines the signature for a combiner class, which can be used to perform the optional "combine" step in a MapReduce operation.
A combiner compacts the locally-produced map output to minimize unnecessary data transfer. Since this is an optimization,
no assumption should be made by the caller about how often (if at all) a combiner is invoked. The output of the
MapReduce task with a combiner enabled will be identical to the output of the MapReduce task running without a combiner.
