//_________________________________________________________________________
//  The AliEMCALLoader gets the TClonesArray and TObjArray for reading
//  Hits, Dgits, SDigits and RecPoints. Filling is managed in the GetEvent()
//  method. The objects are retrived from  the corresponding folders.  
//
//  It also provides acces methods to the calibration and simulation OCDB parameters
