run stops_away.rb to show stops away for all supported stations
create_db.rb takes the data from the spreadsheet below (in CSV form) and turns it into a SQLite DB. Westbound stations that were in common between all the sheets are separated into their own CSV, so there's one more CSV than there are sheets in the spreadsheet.
