### get info
"engineMode=3" allows a client to request the description tags for a segment. This can be restricted with "waypointCatchingRange".
### round trip
"engineMode=4" generate routes returning to the start point.
This needs some parameter:
- roundTripDistance - in meters, how far to generate some helping points (default 1500)
- direction - in degree, the direction to the points (default -1, BRouter uses a random direction)
- roundTripPoints - how many helping point (default 5, 4 around the distance and one end point)
When direction = -1 and with a selection of the profile parameter consider_elevation, consider_forest or consider_river BRouter collects the information about this from the area defined in roundTripDistance and selects a random direction from the quadrant with the best choice of the values. Please keep in mind that the longer the distance, the longer this will take.
