class AliPWGFunc: public TObject

                              AliPWGFunc

 This class implements several function useful to fit pt spectra,
 including but not limited to blast wave models.

 It can return the same functional for as a function of different
 variables: dNdpt vs pt, 1/pt dNdpt vs pt, 1/mt dNdmt vs mt.

 Before getting the function you need, you have to chose the
 variable you want to use calling AliPWGFunc::SetVarType with one of
 the elements of the VarType_t enum.

 TODO: code cleaup, make the naming convention of function more transparent

 Warning: not all variables are implemented for all the functions.
