gio.DBusObjectManagerServer is used to export GDBusObject instances using the standardized org.freedesktop.DBus.ObjectManager
interface. For example, remote D-Bus clients can get all objects and properties in a single call. Additionally, any change in the object hierarchy is broadcast using signals. This means that D-Bus clients can keep caches up to date by only listening to D-Bus signals.
