class AliPHOSTrigger: public AliTriggerDetector

  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.

void GetCrystalPhiEtaIndexInModuleFromTRUIndex(Int_t itru, Int_t iphitru, Int_t ietatru, Int_t& ietaMod, Int_t& iphiMod) const
 This method transforms the (eta,phi) index of a crystals in a
 TRU matrix into Super Module (eta,phi) index.
Bool_t IsPatchIsolated(Int_t iPatchType, const Int_t imod, const Int_t mtru, const Float_t maxamp, const Int_t maxphi, const Int_t maxeta)
void MakeSlidingCell(Int_t mod, TMatrixD& ampmax2, TMatrixD& ampmaxn)
Sums energy of all possible 2x2 (L0) and nxn (L1) crystals per each TRU.
Fast signal in the experiment is given by 2x2 crystals,
for this reason we loop inside the TRU crystals by 2.
void Print(Option_t* opt = "") const
void SetTriggers(Int_t iMod, const TMatrixD& ampmax2, const TMatrixD& ampmaxn)
Checks the 2x2 and nxn maximum amplitude per each TRU and compares
with the different L0 and L1 triggers thresholds. It finds if maximum amplitudes are isolated.
