Bool_t PrepareTransformation(const std::vector< Event * > &)
the identity does not need to be prepared, only calculate the normalization

constructor
virtual const Event * Transform(const Event *const, Int_t cls) const
identity transform returns same event

reding the identity transformation from XML
virtual void MakeFunction(std::ostream &fout, const TString &fncName, Int_t part, UInt_t trCounter, Int_t cls)
creates C++ code fragment of the identity transform for inclusion in standalone C++ class

nothing to initialize
Linear interpolation class.
