docstring: Subtracts series 2 through n from series 1.
  
    Example:
  
    .. code-block:: none
  
      &target=diffSeries(service.connections.total,service.connections.failed)
  
    To diff a series and a constant, one should use offset instead of (or in
    addition to) diffSeries
  
    Example:
  
    .. code-block:: none
  
      &target=offset(service.connections.total,-5)
  
      &target=offset(diffSeries(service.connections.total,service.connections.failed),-4)
