Submodules, yes, subprojects, not so much, unless the committers are the same.  We can definitely
release different artifacts, etc. but the Board has made it pretty clear that umbrella projects
are not good.

+1.  I hope to add in some more Solr hooks in the near future, too, including an implementation
of the ClusteringEngine and other things like DocumentProcessor chains, etc. for classifiers
(help wanted!)
