Slim: Grouping routes by domains

[ghost]

It might be nice to propose grouping routes by domains, as Symfony, Laravel or Lumen already does.

$app->group(['domain' => 'www.example.com'], function($request, $response, $args) {

});

$app->group(['domain' => 'subdomain.example.com'], function($request, $response, $args) {

});

I don't think that belongs in Slim personally. A "sub-domain" inherently means a different domain, which means different context, which means it should be an entire different application. It's not because Symfony or Laravel does it that we should do it either.
