> Similar to the BoostingTermQuery, the BoostingFunctionTermQuery is a SpanTermQuery, but
the difference is the payload score for a doc is not the average of all the payloads, but
applies a function to them instead.  BoostingTermQuery becomes a BoostingFunctionTermQuery
with an AveragePayloadFunction applied to it.
> Also add marker interface to indicate PayloadQuery types.  Refactor Similarity.scorePayload
to also take in the doc id.
