Phalcon\Logger\Multiple::critical()

[BhSimon]

It appears the call to critical() from within multiple logging streams is not working. The following script reproduces the error Fatal error: Call to undefined method Phalcon\Logger\Multiple::critical().

<?php
use Phalcon\Logger,
    Phalcon\Logger\Multiple as MultipleStream,
    Phalcon\Logger\Adapter\File as FileAdapter,
    Phalcon\Logger\Adapter\Stream as StreamAdapter,
    Phalcon\Logger\Adapter\Firephp as Firephp;

class IndexController extends \Phalcon\Mvc\Controller
{
    public function indexAction()
    {
        $logger = new MultipleStream();
        $logger->push( new FileAdapter("../app/logs/test.log") );
        $logger->push( new Firephp("") );
        $logger->debug("[0] Debug");
        $logger->info("[1] Info");
        $logger->notice("[2] Notice");
        $logger->alert("[3] Alert");
        $logger->warning("[4] Warning");
        $logger->error("[5] Error");
        $logger->emergency("[6] Emergency");
        $logger->critical("[7] Critical"); // Does not work
    }
}

This happens with all adapters added to the multiple stream.
This code should have produced the line [7] Critical in both the file adapter and FirePHP console but instead produced the error above.

I haven't tried this code on a different OS, but if I can I will report on the results.
