docstring: Return the text of all tokens from start to stop, inclusive.
          If the stream does not buffer all the tokens then it can just
          return "" or null;  Users should not access $ruleLabel.text in
          an action of course in that case.
  
          Because the user is not required to use a token with an index stored
          in it, we must provide a means for two token objects themselves to
          indicate the start/end location.  Most often this will just delegate
          to the other toString(int,int).  This is also parallel with
          the TreeNodeStream.toString(Object,Object).
docstring_summary: Return the text of all tokens from start to stop, inclusive.
