/**
* 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)
