// Package:         RecoTracker/RoadSearchTrackCandidateMaker
// Class:           RoadSearchTrackCandidateMaker
// 
// Description:     Calls RoadSeachTrackCandidateMakerAlgorithm
//                  to convert cleaned clouds into
//                  TrackCandidates using the 
//                  TrajectoryBuilder framework
