   4         Features:
   5                 *Adds a cancelQueue() method for cancelling the entire queue.
   6                 *All queued files are uploaded when startUpload() is called.
   7                 *If false is returned from uploadComplete then the queue upload is stopped.
   8                  If false is not returned (strict comparison) then the queue upload is continued.
   9                 *Adds a QueueComplete event that is fired when all the queued files have finished uploading.
