Whoops exception callback handler

You would want to use a callback handler.

$whoops = new WhoopsRun();
$handler = new WhoopsCallbackHandler(function($exception, $inspector, $run) {
    //send an email
});
$whoops->pushHandler($handler)->register();

It looks like you are using use statement aliases so I matched your format, but the class is called Whoops\Handler\CallbackHandler.
