* @param integer|array $code If $code is an integer, then the corresponding code/message is
* returned if it exists, null if it does not exist. If $code is an array,
* then the 'code' and 'message' keys of each nested array are added to the default
* HTTP codes. Example:
* returned if it exists, null if it does not exist. If $code is an array, then the
* keys are used as codes and the values as messages to add to the default HTTP
* codes. The codes must be integers greater than 99 and less than 1000. Keep in
* mind that the HTTP specification outlines that status codes begin with a digit
* between 1 and 5, which defines the class of response the client is to expect.
* Example:
*
* httpCodes(404); // returns array(404 => 'Not Found')
*
* httpCodes(array(
* 701 => 'Unicorn Moved',
* 800 => 'Unexpected Minotaur'
* 381 => 'Unicorn Moved',
* 555 => 'Unexpected Minotaur'
* )); // sets these new values, and returns true
*
* httpCodes(array(
* 0 => 'Nothing Here',
* -1 => 'Reverse Infinity',
* 12345 => 'Universal Password',
* 'Hello' => 'World'
* )); // throws an exception due to invalid codes
*
* For more on HTTP status codes see: http://www.w3.org/Protocols/rfc2616/rfc2616-sec6.html#sec6.1
*
* @return mixed associative array of the HTTP codes as keys, and the message
* strings as values, or null of the given $code does not exist.
* @throws CakeException If an attempt is made to add an invalid status code
