Detailed Description

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.
