Description

Track3DKalmanSPS, Track3Dreco and TrackAna modules show non-optimal usage of associations:

larreco/TrackFinder/Track3DKalmanSPS_module.cc
larreco/TrackFinder/Track3Dreco_module.cc
larreco/TrackFinder/TrackAna_module.cc

I notice dubious practise in Track3DKalmanSPS::produce(), Track3Dreco::produce() and TrackAna::anaStitch().

The action I recommend:
- since you use it, #include "art/Framework/Core/FindManyP.h"
- bring the queries FindManyP() out of the loops
- use const std::vector<art::Ptr<T>>& to store the result of FindManyP::at(),
that returns a constant reference
- I am not sure about the purpose of using temporaries (pcoll, sppt) to
initialize FindManyP()

Setting this issue to Resolved.

Per Gianluca's recommendations, FindManyP() pulled out of loops where possible, left as-is when in try{} blocks. Include FindManyP.h, const ref& used where possible, auto temporaries removed.
