  Completely obliterates a queue and all of its contents
  This command completely destroys a queue including all of its jobs, current or past 
  leaving no trace of its existence. Since this script needs to iterate to find all the job
  keys, consider that this call may be slow for very large queues.
  The queue needs to be "paused" or it will return an error
  If the queue has currently active jobs then the script by default will return error,
  however this behaviour can be overrided using the 'force' option.
