/**
 * It allows suspending arbitrary objects for a certain amount of time.
 * After the time expires all the listeners subscribed to the object restoration event will be notified.
 * You can always restore the object explicitly using {@code restore(Path)} before the time expires.
 *
 * Each object is suspended by a certain unique path (net.devromik.suspender.Path).
 * A path has the following format: /segment_1/segment_2/.../segment_N.
 * A path must have at least two segments.
 * Paths are intended for performing hierarchical grouping of suspended objects.
 * Grouping allows you to work with the suspended objects on a group level.
 * For example, it is possible to explicitly restore a whole group of suspended objects.
 *
 * Use the {@code hasObjectsSuspendedBy(Path)} method to check if there are any objects
 * suspended by a path with the '/A/B/C' prefix (for example: '/A/B/C', '/A/B/C/D/E').
 * To restore all these objects, use the method {@code restore(Path)}.
 *
 * You can get notifications on object restoration by registering a listener:
 * {@code addRestoredObjectListener(RestoredObjectListener)}.
