See the example for how to use an this class as a listener.

Responsibilities:

• Listener for ContextModel state events
• Call methods when an event occurs that can be mapped to one of the methods.

  For example if a layer is added the layerAdded method is called.

The following example adds an observer/listener that only reacts to single layer added events... Note that multiple layers being added are ignored .
