	/**
	 * 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)
	 * @since 1.2.2
