/**
 * The preview class
 *
 * This is a clever technique to preview a form without having to set any placeholder page by
 * setting the page templates to singular pages (page.php, single.php and index.php). Setting
 * the posts per page to 1 and changing the page title and contents dynamiclly allows us to
 * preview the form without any placeholder page.
 *
 * This technique requires the theme to have at least the above mentioned templates in the theme
 * and requires to have the WordPress Loop, otherwise we wouldn't be able to set the title and
 * the page content dynamically.
 *
 * The technique is borrowed from Ninja Forms (thanks guys!)
