/**
 * Main class
 *
 * Some general advices:
 * - BuddyPress plugins should always load hooking to bp_include  @see line 104
 * - As this plugin is only playing with the groups component, do not include any
 *   file or run anything before we totally sure the component is active
 * - Always test a plugin having in wp-config.php:
 *   - define( 'WP_DEBUG', true );
 *   - define( 'SCRIPT_DEBUG', true);
 * - Minify the scripts / generate the pot at the very last moment.
 * - Make sure to enqueue scripts only when needed. @see cfbgr_is_restriction_js()
