+/**
+ *  PHP Mikrotik Billing (https://github.com/hotspotbilling/phpnuxbill/)
+ *  by https://t.me/ibnux
+ *
+ * Meta is for save adtional information in database for every existing table
+ *
+ * * Good for Plugin, so plugin don't need to modify existing tables
+ *
+ * Example to put data
+ * if plan need to add point value for loyalty poin
+ * Meta::for("tbl_plans")->set(1, 'point', '24');
+ * it means tbl_plans with id 1 have point value 24, customer will get 24 point for loyalty if buy plan with id 1
+ * You need to create the logic for that, Meta only hold the data
+ *
+ * Example to get data
+ * $point = Meta::for("tbl_plans")->get(1, 'point');
+ * this will return the point value of plan with id 1
+ *
+ * to get all key value
+ * $metas = Meta::for("tbl_plans")->getAll(1);
+ *
+ * to delete 1 data
+ * Meta::for("tbl_plans")->delete(1, 'point');
+ *
+ * to delete all data
+ * Meta::for("tbl_plans")->deleteAll(1);
