No code change just reformatting of header files.

finishing up my reformatting of the source from November/December following the guidelines that were posted.
some extra things I added:
   * Any empty virtual declarations were kept to one line.  
   * Enums were split up into separate lines to promote uniformity across all headers. ( each header file had a different style for enums)
