 * This deals with viz admin settings when viz parameters can have
repeating groups.
 * It's still not the same code base as the form and table code so
refactoring at some
 * point would be good.
 * Not here we clone the actual /admin/com_fabrik/elements/ js classes
 * where as for forms and tables we have a controller class - called
admin.js in the plugin folder
 * to deal with cloning
