//___________________________________________________________
//  Class for trigger analysis.
//  Digits are grouped in TRU's (384 cells? ordered fNTRUPhi x fNTRUEta). 
//  The algorithm searches all possible 4x4 cell combinations per each TRU, 
//  adding the digits amplitude and finding the maximum. Maximums are compared 
//  to triggers threshold and they are set. Thresholds need to be fixed. 
//  Last 2 modules are half size but they are treated as fullsize, then their 
//  TRU should be smaller. When this is fixed, class will be updated. 
//  Usage:
//
//  //Inside the event loop
//  AliEMCALTrigger *tr = new AliEMCALTrigger();//Init Trigger
//  tr->SetL0MBPbPbThreshold(500);
//  tr->SetL0MBppThreshold(100);
//  tr->SetL1JetLowPtThreshold(1000);
//  tr->SetL1JetMediumPtThreshold(10000);
//  tr->SetL1JetHighPtThreshold(20000);
//  tr->Trigger(); //Execute Trigger
//  tr->Print(""); //Print results
//  //are printed
