numbr muon layers
use state setter in SimpleNagation
no regression in test
Cosmic migrated and tested
print muon as well
Migrated NuonNavigationSchool as well
propagate NavSchool to BaseCkfTrajectoryBuilder
fix muon test
remove cout
fix beam halo, not migrated
remove cout
fix Track Producers
fix next layer call in SimpleNavigableLayer::compatibleLayers
Remove NavigationSetter from DQM/DTChamberEfficiency
Remove NavigationSetter from DQM/TrackEfficiencyMonitor
Remove NavigationSetter from RecoEgamma
Use NavigationSchool::nextLayers in MuonCkfTrajectoryBuilder
Use NavigationSchool::compatibleLayers() in StandAloneMuonFilter
Use NavigationSchool::compatibleLayers() in StandAloneTrajectoryBuilder
Use NavigationSchool::compatibleLayers() in MuonTrackAnalyzer
