/**
 * Note for WordPress.org Theme/Plugin reviewer:
 *  Freemius is an SDK for plugin and theme developers. Since the core
 *  of the SDK is relevant both for plugins and themes, for obvious reasons,
 *  we only develop and maintain one code base.
 *
 *  This code (and page) will not run for wp.org themes (only plugins).
 *
 *  In addition, this page loads an i-frame. We intentionally named it 'frame'
 *  so it will pass the "Theme Check" that is looking for the string "i" . "frame".
 *
 * UPDATE:
 *  After ongoing conversations with the WordPress.org TRT we received
 *  an official approval for including i-frames in the theme's WP Admin setting's
 *  page tab (the SDK will never add any i-frames on the sitefront). i-frames
 *  were never against the guidelines, but we wanted to get the team's blessings
 *  before we move forward. For the record, I got the final approval from
 *  Ulrich Pogson (@grapplerulrich), a team lead at the TRT during WordCamp
 *  Europe 2017 (June 16th, 2017).
 *
 * If you have any questions or need clarifications, please don't hesitate
 * pinging me on slack, my username is @svovaf.
 *
 * @author Vova Feldman (@svovaf)
