NotifableProtocol

Overview

This is a simple protocol to make setting up basic notifications very easy.

It provides access to a notificationCenter property. This should be initialized with a default of NotificationCenter.default in the initializer, for testing purposes.

It also provides a simple interface for setting up notifications where the object is nil and the observer is self. Do this by calling setupNotifications(...) wherever you would normally do so, and pass in self and an array of Notification.Name that you wish to observe.

The protocol will also ask you to conform to handleNotifications(...) wherein you should do a basic switch on the notification name and then take the appropriate action.
