Use proper spectrometer specific map for hodoscope decoding.
  Was hardwired to HMS, so SOS was getting HMS hodoscope data.
Script to display SOS hodoscope hit maps
Make data members of raw hit classes private.
  Friend the detector classes that need access to the private members.
  May later want to use member functions to access the data.
Clean up some compiler warnings.
Edit some comments to help with THtml generated documentation.
Remove unneeded THcHitList:: from THcHitList method calls in detector classes.
