Create a separate extension for helper functions

[akrabat]

Also add base_url Twig function.

The method name seem to communicate one thing while doing something else IMO. I would actually prefer to register the extension manually and doing it externally.

You mean registerExtension ?

I kept that so that the set up of the extension remains:

$container->register(new \Slim\Views\Twig('path/to/templates', [
    'cache' => 'path/to/cache'
]));

which is nice and simple to use. I'm not wedded to it though and am happy enough to remove the method and change the README.

if thats the case its probably better to make that method private, Having it as public confuses me.

Although saying that, I still think most users are happy to register it themselves as this is how Slim-Views currently works plus it is easier to override path_for and base_url with my own extension.

[akrabat]

Rebased, removed registerExtension and updated README.

[silentworks]

The README doesn't look correct to me.

Try now!
