 * 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 flags:
 *
 *  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

// specifying define.amd.jQuery = true. Register as a named module,
// since jQuery can be concatenated with other files that may use define,
// but not use a proper concatenation script that understands anonymous
// AMD modules. A named AMD is safest and most robust way to register.
// Lowercase jquery is used because AMD module names are derived from
// file names, and jQuery is normally delivered in a lowercase file name.
// Do this after creating the global so that if an AMD module wants to call
// noConflict to hide this version of jQuery, it will work.
