/**
 * Gravity Perks // GP Terms of Service Field // Add Support for Using Shortcodes in Terms Field
 * http://gravitywiz.com/documentation/gp-terms-of-service/
 *
 * This plug-in-play snippet adds support for shortcodes in terms. It will automatically convert the ToS fields for the given
 * form into the HTML-enabled version (default uses <textarea> which does not support HTML).
 *
 * One way this snippet can be used is in conjuction with the [Post Content Shortcodes](https://wordpress.org/plugins/post-content-shortcodes/)
 * which provides a shortcode to retrive the content of a post. You can keep your terms in a single post and then use a
 * shortcode (i.e. [post-content id="12"])to display those terms in all of your ToS fields.
