( self, instring )
Extension to scanString, to modify matching text with modified tokens that may
           be returned from a parse action.  To use transformString, define a grammar and
           attach a parse action to it that modifies the returned token list.
           Invoking transformString() on a target string will then scan for matches,
           and replace the matched text patterns according to the logic in the parse
           action.  transformString() returns the resulting transformed string.
