Chris Male updated LUCENE-3232:
-------------------------------
Description:
Solr makes use of the MutableValue* series of classes to improve performance of
grouping by FunctionQuery (I think). As such they are used in ValueSource
implementations. Consequently we need to move these classes in order to move
the ValueSources.
As Yonik pointed out, these classes have use beyond just FunctionQuerys and
might be used by both Solr and other modules. However I don't think they
belong in Lucene core, since they aren't really related to search
functionality. Therefore I think we should put them into a Common module,
which can serve as a dependency to Solr and any module.

I'll also use this issue to establish the Queries module where the
FunctionQueries will lie.
