Ideas
* import from gtfs (partly done - lua script)
-> specification of columns in import function
* better end user UI (more clever)
* meredith improvements (filters - partly done)
* example page (probably Szeged)
* better docs
* nice pictures of route types
* fix szeged trip_id bug
* instalation instruction
* open and run packages
* more timetable-like editor for stop_times (like options one in core)
Ideas for future
* display stations and lines on map (openlayers)
