Description

It would be nice if CellTokenStreams were re-used, which are kinda heavy. This is possible without changing the API thanks to LUCENE-5634. PrefixTreeStrategy.createFields() should return Field subclasses that override TokenStream tokenStream(Analyzer analyzer, TokenStream reuse) that in turn examine re-use to ensure it's a CellTokenStream, and then re-use it if possible or create anew.

Completing the re-use, it would be good if TreeCellIterator could be re-used, which might include the getWorldCell value.
