/*
 Description: ESProducer to get the quark-gluon likelihood object "QGLikelihoodSystematicsObject"
              from record "QGLikelihoodRcd". 
 
 Implementation:
     Completely trivial, simply returns the QGLikelihoodSystematicsObject to the user. There is only
     one QGLikelihoodSystematicsObject object in each record.
