/**
 * Fired when the plugin is uninstalled.

 * When populating this file, consider the following flow of control:
 *
 * - This method should be static.
 * - Check if the $_REQUEST content actually is the plugin name.
 * - Run an admin referrer check to make sure it goes through authentication.
 * - Verify the output of $_GET makes sense.
 * - Repeat with other user roles. Best directly by using the links/query string parameters.
 * - Repeat things for multisite. Once for a single site in the network, once sitewide.
