     A Scanner is used to read tokens from a stream of characters

       See the docstrings of the individual methods for more
       information.
-

       read() --> (value, text)
         Reads the next lexical token from the stream.
-

       position() --> (name, line, col)
         Returns the position of the last token read using the

-
