I'm using a theme that has a very robust customizer and I want users other than an admin to be able to use the customizer so they can customize what their site looks like. The URL for the customizer is at: `http://localhost/mulitsite1/wp-admin/customize.php` Is there a way that I can give access to this page for someone that has an editor type role without modifying the core Wordpress `wp-admin/customize.php` file?
