 /*
  * Create a callback list using the following parameters:
  *
  *      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
