 * This plugin generates Mapbox Vector tiles that show the internal
 * routing geometry and speed values on all road segments.
 * You can use this along with a vector-tile viewer, like Mapbox GL,
 * to display maps that show the exact road network that
 * OSRM is routing.  This is very useful for debugging routing
 * errors
