/**
 * Simple app implementation to work with MainWindows.
 * We still need to have this and cannot create the app on-the-fly from the window itself
 * because we need to go through the {@link ApplicationRunner} first so it can perform
 * initialization tasks like setting jface realm and creating a display.
 * Otherwise the window tries to create a model object which could be using
 * some jfacedatabinding observables that won't get any Realm exploding
