.. Route segments are found during interval refresh
.. Config/routes.xml only holds config now
.. The fingerprint for a rideitem includes the route
fingerprint now so it will refresh automatically
when the routes config changes
.. if no routes are defined then no work is done, so the
amount of work is really defined by the user
NOTE: RouteWindow, and now, RouteItem will need to
be reworked and fixed up for v4.0
