Since v0.1.1, a lot of work has gone into a script for building our own Levenshtein automata. Now we can support transpositions as edit operations, and make use of a nice speed-up that is coded into the Levenshtein automata.
Also, there's a lot of cleanup, renaming and re-factoring. Not as much as I'd wish, though. It's a long way to go before we can call this a clean and tidy project.
