- added a unicode ASCII-fiying addition to the fingerprinting functions
- removed all distance functions for kNN that didn't seem to do anything useful
- added the ability to indicate what value to use as cluster centroid by simply clicking on it
(this is useful for those names that have non-ASCII chars that might not even be on your keyboard.. and cut/paste is error prone/cumbersome)
- added a 10x multiplier to the PPM compression distance which makes it more aligned with the levenshtein ones
- made sure that we construct a phonetic fingerprint for the whole string and not just the beginning subset
(performance is still not ideal but it's now reasonable)
