// 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.
