/**

* Loop Add to Cart

* This template can be overridden by copying it to yourtheme/woocommerce/loop/add-to-cart.php.

* HOWEVER, on occasion WooCommerce will need to update template files and you

* (the theme developer) will need to copy the new files to your theme to

* maintain compatibility. We try to do this as little as possible, but it does

* happen. When this occurs the version of the template file will be bumped and

* the readme will list any important changes.

* @see         https://docs.woocommerce.com/document/template-structure/

* @package     WooCommerce\Templates

* @version     3.3.0
