/**
 * Sliders
 *
 * General structure for the sliders, portfolio and gallery pages (and other similar)
 * where you are able to add many items for each post of a custom post type.
 *
 * The logic is:
 * - each custom post type will be a general section (Sliders, Portfolios, Galleries, etc..)
 * - each post of a custom post type will be each individual element (a slider, a portfolio, a gallery, etc...)
 * - each post will contain several configurations and an array with all elements of each section,
 * all this in several custom post meta of the post
 *
 * Examples:
 * $args = array(
 *
 *     'name' => '',    // nome generale della sezione (usato nel menu e in qualche label delle pagine admin)
 *     'icon_menu' => '',  // url dell'icona da far apparire nel menu, accanto al name
 *     'settings' => array(),   // insieme di opzioni per la pagina di configurazione
 *     'settings_item' => array(),   // insieme di opzioni per la pagina di configurazione del singolo elemento
 *     'labels' => array(
 *         'item_name_sing' => ''  // nome dell'elemento singolo al singolare (slide, work, photo, etc...)
 *         'item_name_plur' => ''  // nome dell'elemento singolo al plurale (slides, works, photos, etc...)
 *     ),
 *
 * );
 *
 * $yit->getModel('cpt_unlimited')->add( 'sliders', $args = array() );
 * yit_add_unlimited_post_type( 'sliders', $args );
