//  Class for trigger analysis.
//  Digits are grouped in TRU's (Trigger Units). A TRU consist of 384 cells 
//  ordered fNTRUPhi x fNTRUZ. The algorithm searches all possible 2x2 and 
//  nxn (n multiple of 4) 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. 
//  Last 2 modules are half size in Phi, I considered that the number 
//  of TRU is maintained for the last modules but final decision has not 
//  been taken. If different, then this must to be changed. 
//  Usage:
//
//  //Inside the event loop
//  AliEMCALTrigger *tr = new AliEMCALTrigger();//Init Trigger
//  tr->SetL0Threshold(100);
//  tr->SetL1JetLowPtThreshold(1000);
//  tr->SetL1JetMediumPtThreshold(10000);
//  tr->SetL1JetHighPtThreshold(20000);
//  tr->Trigger(); //Execute Trigger
//  tr->Print(""); //Print results
