class TVirtualMC: public TNamed

   Virtual MC provides a virtual interface to Monte Carlo.
   It enables the user to build a virtual Monte Carlo application
   independent of any actual underlying Monte Carlo implementation itself.

   A user will have to implement a class derived from the abstract
   Monte Carlo application class, and provide functions like
   ConstructGeometry(), BeginEvent(), FinishEvent(), ... .
   The concrete Monte Carlo (Geant3, Geant4) is selected at run time -
   when processing a ROOT macro where the concrete Monte Carlo is instantiated.
