This adapter is a good example for demonstrating how to use annotation managers. Annotation managers are used to add (soft) annotations to program elements driven by some Java code (programmatically). Annotation managers are added to the context an will be chained to other existing annotation managers (potentially added by other adapters). An annotation manager must implement the `manageAnnotation` method, that will tell if a given annotation should be added, removed, or left unchanged on a given element. If the annotation has parameters, an annotation manager shall implement the `getAnnotationValue` in order to specify the values.
