PSR-3 Logger support

Thanks for the recommendation, but Phalcon is a highly decoupled framework and our Logging component is not a dependency of other components, you can use Monolog or any other component for logging without problem,

For example, to log the database queries sent to the database server using Monolog:

$eventsManager = new Phalcon\Events\Manager();

$log = new Monolog\Logger('name');
$log->pushHandler(new Monolog\Handler\StreamHandler('logs/db.log', Logger::WARNING));

//Listen all the database events
$eventsManager->attach('db', function($event, $connection) use ($log) {
    if ($event->getType() == 'beforeQuery') {
        $log->addDebug($connection->getSQLStatement());
    }
});

//Assign the eventsManager to the db adapter instance
$connection->setEventsManager($eventsManager);

//Execute some SQL statement
$connection->insert(
    "products",
    array("Hot pepper", 3.50),
    array("name", "price")
);

here is typo, should be $logger than $log please correct and remove my comment :)

thanks @doit76, corrected

thanks for the example @Phalcon I see the concept more clearer
