PRELIMINARY MkFinderV2p2

[osschar]

First implementation of V2p2 track building.
Currently set up for best-hit-like search over single layers.

The most important additions are in the new class MkFinderV2p2, the new supporting
classes (MkBins, HotTub) and MiniPropagators (Hermite 3D interpolation and plane
intersection solver).

Needs to be rebased onto master.

Changes

• RecoTracker/MkFitCMS/standalone/mkFit.cc

  • Add option --build-mimi-v2p2, setting Config::mimiUseV2p2 to true.

• RecoTracker/MkFitCMS/standalone/buildtestMPlex.cc

  • In runBtpCe_MultiIter(), if Config::mimiUseV2p2 is true, run
    MkBuilder::findTracksStandardv2p2() instead of findTracksCloneEngine().

• RecoTracker/MkFitCMS/standalone/Shell.cc

• RecoTracker/MkFitCMS/standalone/Shell.h

  • In ProcessEvent(), if Config::mimiUseV2p2 is true, run
    MkBuilder::findTracksStandardv2p2() instead of findTracksCloneEngine().
  • Add SetUseV2p2(bool) to set value of Config::mimiUseV2p2.
  • Add FindInterestingSimTracks() helper for selecting tracks with specific
    hit patterns.
  • Prototype REve stuff for showing tracks and hits, ShowSimTrack().

• RecoTracker/MkFitCore/interface/SteeringParams.h

  • Add ability for double layer in LayerControl.
  • Add helper functions for filling up layer-plan with double (swtiched)
    layers.

• RecoTracker/MkFitCore/src/KalmanUtilsMPlex.cc

• RecoTracker/MkFitCore/src/KalmanUtilll pepesMPlex.h

  • Move common charge-flip detection code to inline kalmanCheckChargeFlip().

• RecoTracker/MkFitCore/src/Matriplex/Matriplex.h

  • Add (const) T* Elements(i,j) for direct access to sub-aray and
    loadElements(i,j, const T* src) for seting them.
  • Add atan(), fast_atan() and corresponding operators.

• RecoTracker/MkFitCore/src/Matrix.h

  • Add typedefs MPlex3V and MPlex4V.

• RecoTracker/MkFitCore/src/MiniPropagators.cc

• RecoTracker/MkFitCore/src/MiniPropagators.h

  • In propagate_to functions add up alpha, do not reset to 0 first.
  • Add classes Hermite3D and Hermite3DOnPlane for trajectory interpalotion
    within two points (layer boundaries) and for doing trajectory-plane
    intersection.
  • Use vector funcs in Matriplex, remove local ones.

• RecoTracker/MkFitCore/src/MkBuilder.cc

  • Simplifed findTracksStandardv2p2() -- most logic is MkFinderV2p2 now.

• RecoTracker/MkFitCore/src/MkFinder.cc

  • Move local class Bins (used by selectHitIndicesV2) to a new top-level class, MkBins.
  • Remove old prototype for V2p2, now in new file MkFinderV2p2.cc.

• RecoTracker/MkFitCore/src/PropagationMPlex.h

• RecoTracker/MkFitCore/src/PropagationMPlexPlane.cc

  • Restructure to make it possible to do propToPlane() in full and
    with pre-computed path-length / track parameters.
  • propagateHelixToPlaneMPlex() and helixAtPlane() get a new MPlexQF-ptr argument.

New Files

• RecoTracker/MkFitCore/src/HotTub.h

  • Classes HotTubItem, HotTub and HotTubConsumer for storing and managing
    a smallish, rabidly changing set of objects with minimal memory
    allocation overhead.

• RecoTracker/MkFitCore/src/MkBins.cc

• RecoTracker/MkFitCore/src/MkBins.h

  • Class MkBins for setting up of layer / layer-pair queries
    related to bin ranges

• RecoTracker/MkFitCore/src/MkFinderV2p2.cc

• RecoTracker/MkFitCore/src/MkFinderV2p2.h

  • Steering code for the new hit preselection and track finding.

Minor Changes

• RecoTracker/MkFitCore/interface/TrackerInfo.h

  • Use ROOT::Math::Cross() instead of hand-written expr.

• RecoTracker/MkFitCore/interface/TrackStructures.h

  • Comment fix.

• RecoTracker/MkFitCore/interface/MatrixSTypes.h

  • Add formatting options to dumpMatrix().

• RecoTracker/MkFitCore/interface/MkJob.h

  • Make get_mask_for_layer() const.

• RecoTracker/MkFitCore/src/Hit.cc

  • Improve formatting in print(MeasurementState&).

• RecoTracker/MkFitCore/src/Track.cc

  • Improve formatting of some debug print functions.

• RecoTracker/MkFitCore/standalone/Event.cc

• RecoTracker/MkFitCore/standalone/Event.h

  • Add a new debug printout function for track + hits.
