/** Attachable tag. Can be a child of any tag and can have any actor tag children. Adds a {@link ClickListener} to the
 * parent actor. Each time the parent is clicked, actors that are children of listener tag will be added to the stage.
 * Useful for "delayed" adding of actors - for example, one can easily define a dialog that will be shown each time a
 * certain actor is clicked. Note that is not simply an equivalent of
 * {@link com.github.czyzby.lml.parser.impl.tag.macro.ClickListenerLmlMacroTag click listener macro}: macro parses
 * template between its tags after event occurs (so actor creation is delayed). When using this tag, actors are created
 * along the rest of the template - they are simply not added to the stage immediately, but otherwise they are parsed
 * like any other actors and can access local variables.
 *
 * <p>
 * Mapped to "onClick", "clickListener".
