// Package:         RecoTracker/RoadMapMakerESProducer
// Class:           RoadMaker
// 
// Description:     Creates a Roads object by combining all
//                  inner and outer SeedRings into RoadSeeds
//                  and determines all Rings of the RoadSet
//                  belonging to the RoadSeeds.
