Fixed congressperson model, < not << in class inheritance
Rewrote migration and models to accomodate pluralization. migration/table should be congress_people, so model is CongressPerson
Tested DB, added dummy data, successfully tested validations
Changed birthdate to string field b/c of trouble converting to datetime on CSV import. Worry about it later!
Wrote data import; imported; realized I need state column and to keep first/last name separate. Rewrote migration and importer, about to redo drop/create/migrate/seed.
Reverting to name instead of first/middle/last, because no other way to verify uniqueness. Rewrote last_name method for alphabetizing.
Realized name problem before might have been b/c I did first_name, not firstname. Sticking to reversion anyway. Populated.
Finally got PN validation to work without invalidating half my database! yay! main.rb code works correctly now too.
