//  Class for trigger analysis.
//  Digits are grouped in TRU's  (Trigger Units). A TRU consists of 384 
//  modules ordered fNTRUPhi x fNTRUEta. The algorithm searches all possible 2x2 
//  and nxn (n is a multiple of 2) cell combinations per each TRU,  adding the 
//  digits amplitude and finding the maximum. If found, look if it is isolated.
//  Maxima 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.  
//  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 decision not taken. 
//  If different, then this must be changed. 
//  Usage:
//
//  //Inside the event loop
//  AliEMCALTrigger *tr = new AliEMCALTrigger();//Init Trigger
//  tr->SetL0Threshold(100); //Arbitrary threshold values
//  tr->SetL1GammaLowPtThreshold(1000);
//  tr->SetL1GammaMediumPtThreshold(10000);
//  tr->SetL1GammaHighPtThreshold(20000);
//  ...
//  tr->Trigger(); //Execute Trigger
//  tr->Print(""); //Print results
