Creates a LatLonSelection that will select the link at the supplied location with the specified heading. If the link permits travel in both directions then the edit will be applied to just one direction if it is within 20 degrees of the supplied heading. Locations should be chosen such that there is only one link at that location, to prevent ambiguities. For example, it is recommended to avoid specifying a location that is near an intersection between two or more links.
