   *	options: an optional list of space-separated options that will change how
   *			the callback list behaves or a more traditional option object
   *
   * By default a callback list will act like an event callback list and can be
   * "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

        It also means that features like `useStickyClasses` takes on styles like `position: fixed`.
