Function documentation

~AliEMCALClusterizer()

 dtor
Already deleted in AliEMCALReconstructor.

void DeleteRecPoints()

 free the cluster array

void DeleteDigits()

 free the digits array

void Calibrate(Float_t& amp, Float_t& time, const Int_t cellId)

 Convert digitized amplitude into energy, calibrate time
 Calibration parameters are taken from OCDB : OCDB/EMCAL/Calib/Data

void GetCalibrationParameters()

 Set calibration parameters:
 If calibration database exists, they are read from database,
 otherwise, they are taken from digitizer.
 It is a user responsilibity to open CDB before reconstruction,
 for example:
 AliCDBStorage* storage = AliCDBManager::Instance()->GetStorage("local://CalibDB");

void GetCaloCalibPedestal()

 Set calibration parameters:
 if calibration database exists, they are read from database,
 otherwise, they are taken from digitizer.

 It is a user responsilibity to open CDB before reconstruction,
 for example:
 AliCDBStorage* storage = AliCDBManager::Instance()->GetStorage("local://CalibDB");

void Init()
