------------------------------------------------------------------------
Attached new patch.
* Extract collector from JoinUtil and named it TermsCollector.
* TermsCollector uses BytesRefHash.
* Renamed TermSetQuery to TermsQuery.
* TermsQuery uses sorted ByteRefs[]
* TermsCollector has two concrete impl. One for single value per field and one
for multiple values per field.
* Moved the classes for query time joining under the package
o.a.l.search.join.query
* Added documentation.
The JoinUtil is now just a convience class.
Should we add the existing block joining classes under o.a.l.search.join.index
or o.a.l.search.join.block?
I think this patch is ready to get committed.
