First pass at multi-clause locality georeferences including loctypes F and FOH.
Big refactor on models with Clause, Georef, and Locality.
Clean up indexes.
Localities having commas in them now double-quoted for csv output. Added (strangely) missing heading strings.
Retokenizing (normalizing) the whole locality as much as possible before predictions. Solves many prediction errors without any retraining. Better handling of fractions in parsing.
Cleanup.
