The Route Control Points are a collection of lat/lng pairs which are used to influence a regular route if provided in the route request.
Each Route Control Point (RCP) has the following attributes:
|radius||Radius of Influence (miles/km)|
|weight||Weight value used to avoid specified location. Must lie between 0.1 and 100.0|
Route control point attributes are comma separated values and they must appear in a fixed order (i.e. latitude, longitude, radius, weight).
