Found that on the Mac ICG was ignoring all of header files comments in ${TRICK_HOME}/include because it had the relative directory "include" listed as a system path. Comments were only processed if it wasn't in a system directory. Changed the check to use our function that checks to see if a header is in user or Trick code, basically the same check, but it only uses full paths and doesn't get confused with "include".
refs #63
Changed all header file once include variables to follow the same naming
convention and not start with any underscores. Also deleted old
incorrect copyright notices. Also removed $Id: tags from all files.
Fixes#14. Fixes#22.
