  74 These functions are the ones that a specific implementation must
  75 define.

  77 =head2 display_name
  78
  79  Title   : display_name
  80  Usage   : $string    = $obj->display_name()
  81  Function: A string which is what should be displayed to the user
  82            the string should have no spaces (ideally, though a cautious
  83            user of this interface would not assumme this) and should be
  84            less than thirty characters (though again, double checking
  85            this is a good idea)
  86  Returns : A scalar
  87  Status  : Virtual

  97 =head2 description
  98
  99  Title   : description
 100  Usage   : $string    = $obj->description()
 101  Function: A text string suitable for displaying to the user a
 102            description. This string is likely to have spaces, but
 103            should not have any newlines or formatting - just plain
 104            text. The string should not be greater than 255 characters
 105            and clients can feel justified at truncating strings at 255
 106            characters for the purposes of display
 107  Returns : A scalar
 108  Status  : Virtual
