Made colorScheme and typographyScheme properties in the class interfaces for all our examples.
Moved theming away from example inits and into viewDidLoad
Small update for slider example to allow it to grab the theming properly.

The `BottomNavigationTypicalUseExample` has a retain cycle in the
`dispatch_after` block it uses to update the badge value. This causes
example VCs to be accumulated if they are opened repeatedly. A simple
fix is to keep a weak reference in the dispatched block making the next
update call a no-op.
