Initialize Rolodex (#2569)

Creates the start of the Rolodex app.

Sets up the app with the initial routes setup. Since the native Contacts
app does not open on its home screen, and instead opens on the default
list of contacts, it felt important to set that up first. Some basic app
state management is also setup for managing contact lists across the
app.

Boilerplate visuals are setup for two of the screens. Improved fidelity
will come later.
