//       Class : MultiplexStream
// Description : This is a special ostream that forwards the data that
//               is written to it to any number of other sources, for
//               instance other ostreams, or explicitly to a disk file
//               or to system logging utilities.  It's a very handy
//               thing to set Notify to refer to when running in batch
//               mode.
