Data model

The internal model used, GTFS', is close to GTFS but simplified / normalized / expanded for ease of use.

The main differences are:

• A calendar is a simple list of calendar dates (there is no date range, day of the week and positive/negative exceptions anymore).
• All optional fields with a default value are set (for example, pickup/dropoff types)
• Missing stop times are correctly interpolated, and marked with a flag.
• Shape distances are converted to meters and computed if missing.
• All frequencies are expanded to normal trips, and marked with a flag (TODO).
• ...
