Got rid of unused getScheduleTimesMap().
Can now process arrivals/departures for missionBay so that can write out
arrival/departures to the SFMTA tech shuttle API.
Changed Trip so that the schedule times are stored in an array instead
of a map so that schedule info works even if a stop is used several
times in a trip. This is important for loop routes where the stop at the
end of the trip is the same as the first stop. Also important for
figure-8 routes where the same stop is traversed multiple times.

Also added getStop() so that it can be used by Mission Bay to send stop
info to the SFMTA API.
Finished up ability to send stop info to the SFMTA API.
