0002  Description: ESProducer to get the quark-gluon likelihood object "QGLikelihoodObject"
0003               from record "QGLikelihoodRcd".
0004
0005  Implementation:
0006      Completely trivial, simply returns the QGLikelihoodObject to the user. There is only
0007      one QGLikelihoodObject object in each record.
