class AliAnalyseLeadingTrackUE: public TObject

 constructor

 remove injected signals (primaries above <maxLabel>)
 <tracks> can be the following cases:
 a. tracks: in this case the label is taken and then case b.
 b. particles: the first stable mother is searched and checked if it is <= <maxLabel>
 <mcObj> can be AOD (TClonesArray) or ESD (AliMCEvent)

 remove particles from weak decays
 <tracks> can be the following cases:
 a. tracks: in this case the label is taken and then case b.
 b. particles: it is checked if IsSecondaryFromWeakDecay is true
 <mcObj> can be AOD (TClonesArray) or ESD (AliMCEvent)

 Returns an array of particles that pass the cuts, if arrayMC is given each reconstructed particle is replaced by its corresponding MC particles, depending on the parameter onlyprimaries only for primaries
 particleSpecies: -1 all particles are returned
                  0 (pions) 1 (kaons) 2 (protons) 3 (others) particles
 speciesOnTracks if kFALSE, particleSpecies is only applied on the matched MC particle (not on the track itself)
 Passing down the Double_t* evtPlane (range [-pi/2,pi/2]) will apply a phi cut with respect to the eventplane between fTrackPhiCutEvPlMin and fTrackPhiCutEvPlMax. For values outside [-pi/2,pi/2], this will be ignored.

 particleSpecies: -1 all particles are returned
                  0 (pions) 1 (kaons) 2 (protons) 3 (others) particles

 Returns track or MC particle at position "ipart" if passes selection criteria
 particleSpecies: -1 all particles are returned
                  0 (pions) 1 (kaons) 2 (protons) 3 (others) particles

 Sort array of TObjArray of tracks by Pt using a quicksort algorithm.

 check if the track status flags are set
