// Package:         RecoTracker/RoadSearchSeedFinder
// Class:           RoadSearchSeedFinderAlgorithm
// 
// Description:     Loops over Roads, checks for every
//                  RoadSeed if hits are in the inner and
//                  outer SeedRing, applies cuts for all 
//                  combinations of inner and outer SeedHits,
//                  stores valid combination in TrackingSeed
