Special matching class for matching whitespace. Normally, whitespace is ignored by pyparsing grammars. This class is included when some whitespace structures are significant. Define with a string containing the whitespace characters to be matched; default is ``" \t\r\n"``. Also takes optional ``min``, ``max``, and ``exact`` arguments, as defined for the :class:`Word` class.
