 Default destructor
void SetBranchStatus()
 Switch on needed branches
void BookHistograms()
 Book histograms
Bool_t AnalyzeEvent()
 Event analysis
Bool_t IsKaonVertex(HepVertex* vtx)
 Return true, if the given vertex is already assigned
 to a kaon decay. Return false otherwise or if
 there are no kaon decays (eg. the K0s finder didn't run).
Bool_t IsLambdaVertex(HepVertex* vtx)
 Return true, if the given vertex is already assigned
 to a kaon decay. Return false otherwise or if
 there are no kaon decays (eg. the K0s finder didn't run).
Bool_t IsConversionVertex(HepVertex* vtx)
 Return true, if the given vertex was already being tagged
 as a photo conversion vertex. Return false otherwise or if
 there are no conversion vertices.
void ReconstructLambdaKinFit()
 Lambda reconstruction from track-pairs assuming being pions using KinFitter
void FindSharedTracks()
TKinFitter PerformFit(HepParticle trk1, HepParticle trk2, AtlIDTrack* trk3, TLorentzVector& FitP_trk1, TLorentzVector& FitP_trk2, TLorentzVector& FitP_trk3, TMatrixD* cov_trk1, TMatrixD* cov_trk2, TMatrixD* cov_trk3)
