There were a few small things in the tests that needed to change to work with Spatial4j v0.2 vs the latest 0.3 snapshot. And I moved/renamed the package and classes a bit to better fit in with Solr.
This is just an FYI. If you want to engage in the discussion about my patch then comment on the JIRA issue. When SOLR-3304 is committed, we'll have to figure out what to do with the strategies marked pending.
