//_________________________________________________________________________  
//  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 
//  2x2 and nxn (n multiple of 2) crystal 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. 
//  Usage:
//
//  //Inside the event loop
//  AliPHOSTrigger *tr = new AliPHOSTrigger();//Init Trigger
//  tr->SetL0Threshold(100);
//  tr->SetL1JetLowPtThreshold(1000);
//  tr->SetL1JetMediumPtThreshold(10000);
//  tr->SetL1JetHighPtThreshold(20000);
//  ....
//  tr->Trigger(); //Execute Trigger
//  tr->Print(""); //Print data members after calculation.
