class AliPerfAnalyzeInvPt: public TNamed

 Implementation of AliPerfAnalyzeInvPt class. It analyzes the output of
 AliPerformancePtCalib.cxx  and AliPerformancePtCalibMC.cxx: via
 AliPerformancePtCalib::Analyse() or AliPerformancePtCalibMC::Analyse()

 Projection of charge/pt vs theta and vs phi resp. histoprams will be fitted with either
 polynomial or gaussian fit function to extract minimum position of charge/pt.
 Fit options and theta, phi bins can be set by user.
 Attention: use the Set* functions of AliPerformancePtCalib.h and AliPerformancePtCalibMC.h
 when running AliPerformancePtCalib*::Analyse()
 The result of the analysis (histograms/graphs) are stored in the folder which is
 a data member of AliPerformancePtCalib*.
