 * Create a callback list using the following parameters:

 *
 * 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)

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

// Note that for maximum portability, libraries that are not jQuery should
