Just a little example of how to stay updated when some data change
Once you subscribe to personRepositoryRead you'll never miss a thing.
You'll be noticed whith the new state when a new person is created,
updated or deleted
All repos have an ItemChanges object that propagates the changes
So all the have to do is respond suitably to them
BTW this is my first project with Kotlin and RxJava 2 so don't take this as the bible. It's just an example
Stay kiwi!
