docstring: Adds allowed values for an option.
  
  The values are merged with the allowed values defined previously.
  
  Instead of passing values, you may also pass a closures with the
  following signature:
  
  function ($value) {
  // return true or false
  }
  
  The closure receives the value as argument and should return true to
  accept the value and false to reject the value.
  
  @param string $option        The option name
  @param mixed  $allowedValues One or more acceptable values/closures
  
  @return $this
  
  @throws UndefinedOptionsException If the option is undefined
  @throws AccessException           If called from a lazy option or normalizer
