-----------------------------------------

bq. I wonder if we should name this module something more specific, eg docvalues? values?

> 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.
