ScheduleViewer error: 'GetStartTime' not defined

[answerquest]

I just git-cloned the transitfeed repo and ran ScheduleViewer (after making the api key hotfix mentioned in #467 ). There seems to be an error happening when we click on any route:

Exception happened during processing of request from ('127.0.0.1', 52468)

It looks like a variable/object GetStartTime is being used before being defined. This doesn't seem like a missing module error or so.

Note: probably because they're both using the same code, location_editor.py is also having the same issue.

for me a quick workaround was to use sorted instead of sort

diff --git a/transitfeed/trip.py b/transitfeed/trip.py
