Make App based on router, which provides url and path
Make App based on router, which provides url and path

App gives informaiton about a specific path
A router has a mapping between a path and a url, and this mapping is
different based on the type of app (sys app, dev app, etc.)

So really, a router is more like a Pathname object and a URI.

So instead of passing a router AND a Pathname into the App, possibly
introducing a bug by passing in an incompatible path+router combination,
we make the router the path.

So this expects an object that responds to #url and #owner and #path
