 * Annotation to declare that the mapped entity will control which labels are added to a node. On save the node's
 * labels will equal the contents of the collection property that this label is applied to, plus the class name or
 * or @NodeEntity label property, if applicable.
 * 

 * If this annotation does not exist or refers to a null property on the mapped entity, then the node's labels
 * will not be managed, that is, left as is.
