Updated the muon beamline build:
  -- Added a attachSyste control based on intersecting linkpts
  MODE Problem remains
  Added a debugMethod object that can trun debug output on
  in the same way as RegMethod.
Merge of the physics card items
  -- this is just because I am going to forget when I back merge
Removal of redundent code
Final update for muBeam :

   The is the merge of Goran Skoro's muon beamline system. This is an
   excellent example of how to build a quick component type model.
