 * Interface to indicate that a question bank column can go in the action menu.
 *
 * If a question bank column implements this interface, and if the {@see edit_menu_column}
 * is present in the question bank view, then the 'column' will be shown as an entry in the
 * edit menu instead of as a separate column.
 *
 * Probably most columns that want to implement this will be subclasses of
 * {@see action_column_base}, and most such columns should probably implement
 * this interface.
 *
 * If your column is a simple action, you can probably save duplicated code by
 * using the base class action_column_menuable as an easy way to implement both
 * action_column_base and this interface.
