/**
 * 
 * Marker interface for a View Model. Some additional hints to this layer:
 * 
 * 
 * 
 * Never create a dependency to the view in this layer - if you have to create a new view after a business step, notify
 * the view with the {@link NotificationCenter} or a callback that the view can create the new view. When you write a
 * new {@link View} you should create the associated {@link ViewModel} with tests before.
