/* ================================================================================================================
 *
 * This is the "notify me" plugin from the plugin hunt theme. Written very similar to IA when I wrote it
 * already has lots of useful things like:-
 * - settings page for notifications per WP users (disabled for now)
 * - browser push notifications for UNREAD notifications
 * have built it in so it does our stuff (upsell stuff + marketing for free)
 * - for INTERNAL team stuff, suggest building the TEAM notifications PRO and include things like @mentions
 * - will write notifications system to also check a JSON file where we can post them notifications from external
 * - e.g. JSON(ID: message) and it marks them as read, then if we want to notify the installs, we can do that ;) 
 * - the EXTENRAL updates is what the 'zbsnotify_reference_id' is for
 *
