Add dual-use TrackParticleMergerAlg; clean up DerivationFrameworkInDet
@dguest was annoyed that we needed to use athena to merge two track collections. Hopefully this makes him less annoyed.
This MR adds a new CP algorithm to TrackingAnalysisAlgorithms
which takes two TrackParticleContainers
and merges them into one to be more easily fed into downstream algorithms.
The old TrackParticleMerger
in DerivationFrameworkInDet
has been removed, along with several bits of legacy code that are not used anymore.
