    Reject a given list of workflows and then clone them. also
    INVALIDATES original dataset, since the clone will have increased
    version number
    This can be used when input workflows are in status: assigened or assignment-approved
    Please use abortAndClone for workflows in status acquired or running open/closed
    The cloned requests have a newly generated RequestName, 
    new timestamp, however -everything- else is copied from the original request.
