/**
   \class   StGenEvent StGenEvent.h "AnalysisDataFormats/TopObjects/interface/StGenEvent.h"

   \brief   Class derived from the TopGenEvent for single-top events

   The structure holds reference information to the generator particles 
   of the decay chains for each top quark and of the initial partons 
   and provides access and administration. The derived class contains 
   a few additional getters with respect to its base class.
