18// Class for trigger analysis.
19// Digits are grouped in TRU's (Trigger Units). A TRU consist of 16x28
20// crystals ordered fNTRUPhi x fNTRUZ. The algorithm searches all possible
21// 2x2 and nxn (n multiple of 2) crystal combinations per each TRU, adding the
22// digits amplitude and finding the maximum. If found, look if it is isolated.
23// Maxima are transformed in ADC time samples. Each time bin is compared to the trigger
24// threshold until it is larger and then, triggers are set. Thresholds need to be fixed.
25// Usage:
26//
27// //Inside the event loop
28// AliPHOSTrigger *tr = new AliPHOSTrigger();//Init Trigger
29// tr->SetL0Threshold(100);
30// tr->SetL1JetLowPtThreshold(1000);
31// tr->SetL1JetMediumPtThreshold(10000);
32// tr->SetL1JetHighPtThreshold(20000);
33// ....
34// tr->Trigger(); //Execute Trigger
35// tr->Print(""); //Print data members after calculation.
