925   * By default a callback list will act like an event callback list and can be

928   * Possible options:

931   *
932   *      memory:                 will keep track of previous values and will call any callback added
933   *                                      after the list has been fired right away with the latest "memorized"

935   *
936   *      unique:                 will ensure a callback can only be added once (no duplicate in the list)

931   *

933   *                                      after the list has been fired right away with the latest "memorized"
