AliFemtoQinvCorrFctn(char* title, const int& nbins, const float& QinvLo, const float& QinvHi)

 fTrack1(NULL),
 fTrack2(NULL)
 set up numerator
  title = "Num Qinv (MeV/c)";

 copy constructor

~AliFemtoQinvCorrFctn()

 destructor

AliFemtoQinvCorrFctn& operator=(const AliFemtoQinvCorrFctn& 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.
  fNumerator->Draw();
fDenominator->Draw();
fRatio->Draw();

AliFemtoString Report()

 construct report

void AddRealPair(AliFemtoPair* aPair)

 add true pair

void AddMixedPair(AliFemtoPair* aPair)

 add mixed (background) pair

void Write()

 Write out neccessary objects

TList* GetOutputList()

 Prepare the list of objects to be written to the output
