//_________________________________________________________________________  
//  Class for trigger analysis.
//  Digits are grouped in TRU's (Trigger Units). A TRU consist of 16x28 
//  crystals ordered fNTRUPhi x fNTRUZ. The algorithm searches all possible 
//  4x4 crystal combinations per each TRU, adding the digits amplitude and 
//  finding the maximum. Maximums are transformed in ADC time samples. 
//  Each time bin is compared to the trigger threshold until it is larger 
//  and then, triggers are set. Thresholds need to be fixed. 
//  Usage:
//
//  //Inside the event loop
//  AliEMCALTrigger *tr = new AliEMCALTrigger();//Init Trigger
//  tr->SetL0Threshold(100);
//  tr->SetL1JetLowPtThreshold(1000);
//  tr->SetL1JetHighPtThreshold(20000);
//  tr->Trigger(); //Execute Trigger
//  tr->Print(""); //Print result, with "deb" option all data members 
//  //are printed
