+// 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.
