An error handling controller prototype

gistfile1.php

<?php
namespace MyApplication\Controller;

use Hydrogen\Controller;
use Hydrogen\TemplateRenderer;

class Error extends Controller
{
    use TemplateRenderer;

    public function error($message = "Server Error", $httpCode = 500)
    {
    	if(PHP_CLI)
    	{
    		$this->render('error.cli.mustache', compact($message));
    	}
    	else
    	{
    		$this->render('error.phtml', compact($message, $httpCode));
    	}
    
    	return $this->response;
    }
}

$this->render is defined by TemplateRenderer, which uses configuration and classes pulled from the Factory (haven't decided how to structure that part yet)
