 copy constructor

 destructor

AliFemtoCorrFctnDEtaDPhi& operator=(const AliFemtoCorrFctnDEtaDPhi& aCorrFctn)

 assignment operator

void Finish()

 here is where we should normalize, fit, etc...
 we should NOT Draw() the histos (as I had done it below),
 since we want to insulate ourselves from root at this level
 of the code.  Do it instead at root command line with browser.
  mShareNumerator->Draw();
mShareDenominator->Draw();
mRatio->Draw();

AliFemtoString Report()

 create report

void AddRealPair(AliFemtoPair* aPair)

 add real (effect) pair

void AddMixedPair(AliFemtoPair* aPair)

 add mixed (background) pair

void WriteHistos()

 Write out result histograms

TList* GetOutputList()

 Prepare the list of objects to be written to the output

void SetDoPtAnalysis(int do2d)
