/** Insertion of accents
  
  Proper handling of accented characters.
  This is class is supposed to handle all LaTeX accents, it
  is also possible that the class will change a bit so that
  it also can handle other special characters (e.g. Hstroke)
  Initiated by Ivan Schreter, later modified by Lgb.
