d72c07b715 latest clustering fixes (the vptree is still too slow though, I'll probably abandon that approach for now)

8ce21461cb getting closer to the desired functionality... still way too slow though

5b079b04b7 - moved from float to double to avoid excessive casting from secondstring
- added a few of the more powerful distances
- fixed a bug in the VPTree builder (although is still not working as I expect it to)

f7b0caa1b8 now kNN clustering is fully operational... not very practical though, needs more work and testing

976c1da5c7 much improved facet clustering dialog and functionality
NOTE: kNN clustering code operational but is not working as expected

c07431fb88 - cataloged all the licenses for the libraries Gridworks depends on
- added the secondstring libraries that contains all sorts of useful string distance functions
- added a java arithmetic coding library (used to implement a string distance based on PPM arithmetic coding)
- added the vicino kNN string clustering library (from MIT's SIMILE)
