any thoughts on adding a little bit more? eg. the examples in controller's README

Most of the Controller examples in the README rely on Advanced Custom Fields. I've followed the JS files with the above, but not sure it's the best use of Controller.

I feel an App.php and Singular.php (or Single.php and Page.php) might be more obvious that it uses the default WordPress template hierarchy. A good example for Single.php could be getting an array of categories the post belongs to as one can expect that with a default WordPress post.

Let me know what you think?

gonna merge for now, we can always re-iterate 👍
