    // Under Raptor, for transit trips, ItineraryMapper converts Path<TripSchedule> directly to Itinerary
    // (the old API response element, within TripPlan). Non-transit trips still use GraphPathToTripPlanConverter
    // to turn A* results (sequences of States and Edges called GraphPaths) into TripPlans which also contain
    // Itineraries.
    // So transit results do not go through GraphPathToTripPlanConverter. It contains logic to find board/alight
    // rules from StopPatterns within TripPatterns, and attach them as machine-readable codes on Legs, but only
    // where you are really boarding or alighting (considering interlining / in-seat transfers).
    // That needs to be re-implemented for the Raptor transit case.
    // - See e2118e0a -> GraphPathToTripPlanConverter#fixupLegs(List<Leg>, State[][]))
    // leg.alightRule = <Assign here>;
    // leg.boardRule =  <Assign here>;
