The routing endpoint plans a route through the waypoints for one of six
profiles, for the people signed in, at most 50 waypoints and 30 plans a
person a minute, nothing kept or logged; refused without BROUTER_URL.
BRouter's GeoJSON is read into points, elevations, climb and descent
above 3 m, turn hints and stretches by surface. Train's running profile
for BRouter, halkyon-run.brf, is a first guess not yet tried on BRouter.
