+ * "fired" multiple times.
+ *
+ * Possible options:
+ *
+ * once: will ensure the callback list can only be fired once (like a Deferred)
+ *
+ * memory: will keep track of previous values and will call any callback added
+ * after the list has been fired right away with the latest "memorized"
+ * values (like a Deferred)
+ *
+ * unique: will ensure a callback can only be added once (no duplicate in the list)
+ *
+ * stopOnFalse: interrupt callings when a callback returns false
