class AliRsnEvent: public TObject

 Default constructor.

 Copy constructor.

 Works in the same way as the copy constructor.

 Destructor (does nothing since there are not owned pointers)

 Assigns to the first argument the reference to the i-th track in the ref event.
 What assignment method to be used will depend on the index and on the type of input.
 If the last argument is kTRUE and an MC is referenced, then both fRef and fRefMC will
 point to the MC particle (pure MC analysis)

 Returns a daughter set using same criteria as SetDaughter

 Setup the first argument to the track identified by the index.
 When available, adds the MC information and references.

 Version #1: ESD tracks

 Setup the first argument to the track identified by the index.
 When available, adds the MC information and references.

 Version #2: AOD tracks

 Setup the first argument to the track identified by the index.
 When available, adds the MC information and references.

 Version #3: ESD v0

 Setup the first argument to the track identified by the index.
 When available, adds the MC information and references.

 Version #4: AOD v0

 Setup the first argument to the track identified by the index.
 When available, adds the MC information and references.

 Version #3: ESD cascade

 Setup the first argument to the track identified by the index.
 When available, adds the MC information and references.

 Version #4: AOD cascade

 Using the label assigned to the daughter, searches for the MC informations:
 -- MC reference
 -- mother

 Using the label assigned to the daughter, searches for the MC informations:
 -- MC reference
 -- mother

 Using the phylosophy of the absolute index, which loops over
 all tracks, V0s and cascades, returns the result of a check
 on it (first argument) based on this criterion:
 1) if the absolute ID is smaller than number of tracks,
    return itself and the type 'track'
 2) if the absolute ID is larger than number of tracks, subtract it
    and if the result is smaller than number of V0s,
    return the corresponding V0 index and type
 3) if the absolute ID is larger than number of tracks + V0s, subtract them
    and if the result is smaller than number of cascades,
    return the corresponding cascade index and type
 The results of this check are stored in the reference arguments, while the outcome of
 the function is kTRUE if one of these checks was successful, otherwise it is kFALSE,
 meaning that the absolute index reached the end.

 Translates a pair made by index + object type into the corresponding
 absolute index, which is set to -1 in case the real index overflows.

 Searches the collection of all particles with given PID type and charge,
 and returns the one with largest momentum, provided that it is greater than 1st argument.
 If one specifies AliRsnPID::kUnknown as type or AliRsnDaughter::kNoPID as method,
 the check is done over all particles irrespectively of their PID.
 If the sign argument is '+' or '-', the check is done over the particles of that charge,
 otherwise it is done irrespectively of the charge.

 Check that input is ESD or AOD

 Assign pointer to MC event.
 If it is an AOD, retrieve the list of MC particles

 basic setters/getters

 getters which convert into allowed input types

 counters/converters of candidates

 leading particle stuff
