 * 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
 *

//      3. Use the same single mechanism to support "private" and "user" data.
//      4. _Never_ expose "private" data to user code (TODO: Drop _data, _removeData)
//      5. Avoid exposing implementation details on user objects (eg. expando properties)
//      6. Provide a clear path for implementation upgrade to WeakMap in 2014

// Register as a named AMD module, since jQuery can be concatenated with other

// to call noConflict to hide this version of jQuery, it will work.

// Note that for maximum portability, libraries that are not jQuery should
// declare themselves as anonymous modules, and avoid setting a global if an
// AMD loader is present. jQuery is a special case. For more information, see
