Clean simple errors from GTFS files
gtfs_clean(gtfs, removeNonPublic = FALSE)gtfs list
logical if TRUE remove routes with route_type missing
Task done:
0. Remove stops with no coordinates 1. Remove stops with no location information 2. Remove stops that are never used 3. Replace missing agency names with "MISSINGAGENCY" 4. If service is not public and removeNonPublic=TRUE then remove it (freight, 'trips' aka charters) (these have a null route_type, so loading into OpenTripPlanner fails if these are present)
