 * An annotation that marks a {@link Job} class as one that makes updates to its
 * {@link JobDataMap} during execution, and wishes the scheduler to re-store the
 * JobDataMap when execution completes. 
 *   
 * Jobs that are marked with this annotation should also seriously consider
 * using the {@link DisallowConcurrentExecution} annotation, to avoid data
 * storage race conditions with concurrently executing job instances.
