Add notification fragment to reference app.

The notification fragment has two pairs of buttons, with one pair at
the top where it will be covered by the heads-up notification (HUN)
and one further down where it won’t be covered by the HUN. Each pair
includes a button to post a notification that will appear as a
heads-up notification and a button to clear the previously posted
notification.
