/**
 * This annotation is placed on an annotation that can be used
 * to indicate a binding between an interceptor (annotated
 * with {@link Interceptor}) and a class to be intercepted
 * (annotated with {@link Intercepted}).
 * 
 * The annotation on which this annotation is placed must
 * have RUNTIME retention and have a Target of TYPE or
 * METHOD (or ANNOTATION_TYPE for transitive bindings).
 * 
 * When an annotation annotated with this annotation is put
 * on an implementation of
 * {@link org.aopalliance.intercept.MethodInterceptor} or
 * {@link org.aopalliance.intercept.ConstructorInterceptor} and
 * which is also annotated with {@link Interceptor} then it becomes
 * associated with that interceptor.  These interceptors will
 * be called on methods of any service annotated with
 * {@link Intercepted} appropriately.
 * 
 * When an annotation annotated with this annotation is
 * used with an hk2 service marked with {@link Intercepted}
 * it can either be put on the entire class, in which case EVERY method
 * of that class will be intercepted, or it can be placed on individual
 * methods of the service to indicate that only those methods should be
 * intercepted.  If it is placed both at the class level and on individual
 * methods then every method will be intercepted.
 * 
 * Annotations annotated with InterceptionBinder are transitive.  In other
 * words if an annotation is annotated with ANOTHER annotation that is
 * marked with InterceptionBinder then any interceptor marked with the other
 * annotation also applies to any service or method marked with this annotation
