 *
 * WordPress Core has a few ways of allowing plugin developers to run things earlier in the app lifecycle.
 * One of this ways is to place a sunrise.php file inside the wp-content directory while setting
 * The SUNRISE constant to true.
 *
 * This tells WordPress that it should load our sunrise file before plugins get loaded and
 * the request is processed. We use this great power to handle domain mapping logic and more.
 * 
 * @since 2.0.0.5 Adds a network admin notice warning that sunrise is still active when Ultimo is deactivated.
 * @since 2.0.0.5 Change return statement to a continue statement to prevent an early exit from the file.
