docstring: Sets the normalizer for an option.
  
  The normalizer should be a closure with the following signature:
  
  function (Options $options, $value) {
  // ...
  }
  
  The closure is invoked when {@link resolve()} is called. The closure
  has access to the resolved values of other options through the passed
  {@link Options} instance.
  
  The second parameter passed to the closure is the value of
  the option.
  
  The resolved option value is set to the return value of the closure.
  
  @param string   $option     The option name
  @param \Closure $normalizer The normalizer
  
  @return $this
  
  @throws UndefinedOptionsException If the option is undefined
  @throws AccessException           If called from a lazy option or normalizer
