> 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.
