Short summary of code changes below.
** RecoTracker/TkSeedGenerator **
Algorithm implemented in RecoTracker/TkSeedGenerator/plugins/MultiHitGeneratorFromChi2.
MultiHitGenerator classes are a generalization of corresponding HitTripletGenerator one; they create OrderedMultiHits, i.e. SeedingHitSets with undefined number of hits (thus allowing both triplets and pairs from the same generator).
** RecoTracker/TkSeedingLayers **
Adding RecoTracker/TkSeedingLayers/interface/OrderedMultiHits.h and adding zero size case to SeedingHitSets
** RecoTracker/IterativeTracking **
Adding python files for triplet-based iter5 and iter6 (both in default and PostLS1 versions):
RecoTracker/IterativeTracking/python/PixelLessTripletStep_cff.py
RecoTracker/IterativeTracking/python/TobTecHybridStep_cff.py
They are included but commented out in iterativeTk_cff.py
** RecoPixelVertexing/PixelTriplets **
moving files from plugins to interface,src so that the library with the needed symbols can be used in other packages (i.e. RecoTracker/TkSeedGenerator)
