 --- PHYSICS LIST : add also the following official Physics Lists 
     for High Energy Calorimetry: LHEP, QGSP; and provide
     a simple way for switching easily from one Physics List
     to another one, using QGSC as default. 
 
 In practice, the selection of the physics list should reduce
 to a simple copy of a file, as follows:
  --- For using LHEP:
        >  cp src/MyPhysicsList.cc-LHEP src/MyPhysicsList.cc
  --- For using QGSC:
        >  cp src/MyPhysicsList.cc-QGSC src/MyPhysicsList.cc
  --- For using QGSP:
        >  cp src/MyPhysicsList.cc-QGSP src/MyPhysicsList.cc


 NB) Notice that, for most calorimeter applications, the 
     faster LHEP Physics List already provides quite a good
     description; however, for a more detailed description,
     either QGSC or QGSP can be used. Keep in mind that these 
     sophisticated models are slower than LHEP.
     Please refer to the Web page:
       http://cmsdoc.cern.ch/~hpw/GHAD/HomePage/index.html
     for more information on these (and others) Physics Lists.
