/**
 * May be applied to extension in order to order extensions.
 * <p>NOTE: Extension installer must implement {@link Ordered} otherwise annotation will not make any effect.</p>
 * <p>Also, may be applied to installer to order installers. Installers ordering may be useful if you have some
 * edge case, which is normally handled by core installer. Without ordering you will have to manually register
 * all installers to place your installer before. With ordered you could simply annotate your installer and it
 * will be executed before default installers. Also, may be used to order your own installers order.
 * Core installers are ordered from 10 to 100 with gap 10 (to simplify injection of custom installers between them).</p>
