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 `Word` class.
