docs: Define expression to be ignored (e.g., comments) while doing pattern
          matching; may be called repeatedly, to define multiple comment or other
          ignorable patterns.
  
          Example::
  
              patt = OneOrMore(Word(alphas))
              patt.parseString('ablaj /* comment */ lskjd') # -> ['ablaj']
  
              patt.ignore(cStyleComment)
              patt.parseString('ablaj /* comment */ lskjd') # -> ['ablaj', 'lskjd']
