*
*     1. In your CPT register_post_type function, set " 'menu_icon' => '', "
*     2. This will make the class for your admin icon .menu-icon-{slug for Custom Post Type name}
*     3. Load a compiled scss stylesheet at wp_head: 
*
*        function add_menu_icons_styles(){
*            wp_enqueue_style( 'screen', get_template_directory_uri() . '/css/dashicons.css', array(), '0.1.0', 'all' );
*        }
