/**
* @description
* The NavController is a navigation stack View Controller modelled off of
* UINavigationController from Cocoa Touch. With the Nav Controller, you can
* "push" new "pages" on to the navigation stack, and then pop them off to go
* back. The NavController controls a navigation bar with a back button and title
* which updates as the pages switch.
*
* The NavController makes sure to not recycle scopes of old pages
* so that a pop will still show the same state that the user left.
*
* However, once a page is popped, its scope is destroyed and will have to be
* recreated then next time it is pushed.
