+/*
+  Class used for extracting the signal from an invariant mass spectrum.
+  It implements the AliDielectronSignalBase class and uses the like-sign
+  substraction method for estimating the signal and background.
+  There is no fitting in this class, only bin counting.
+
+  Example usage:
+   AliDielectronSignalExt *signalProcess = new AliDielectronSignalExt();
+   TObjArray *histoArray = new TObjArray();
+   histoArray->Add(signalPP);                  // the order of putting the histograms in the array is important!!
+   histoArray->Add(signalPM);
+   histoArray->Add(signalMM);
+   signalProcess->SetMethod(AliDielectronSignalBase::kLikeSign);  // or kEventMixing
+   signalProcess->SetIntegralRange(3.0,3.15);   // J/Psi peak
+   signalProcess->SetRebin(2);                  // rebin the histograms
+   signalProcess->Process(histoArray);
+   signalProcess->Draw("stat");
+   signalProcess->Print();
