 * Possible options:

 *
 *      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)

// AMD modules. A named AMD is safest and most robust way to register.
// Lowercase jquery is used because AMD module names are derived from
