                              Detailed Description

                              Duplicate all data passed by the stream operator to two output streams.

                              Can be used as replacement for any OutputStream – for example, forwarding the DBG output simultaneously to screen (TextStream) and serial console (SerialStream).

                              By using template programming, two generic methods are sufficient (which simply forward the input to both).

                              CopyStream::CopyStream ( OutputStream *  first,
                              OutputStream *  second 
                              )
                              inline

                              Constructor.

                              Parameters
                              firstFirst recipient for output passed to this object
                              secondSecond recipient for output passed to this object

                              template<typename T >

                              inline

                              Generic stream operator for any data type.

                              Forwards all input to both recipients.

                              Uses template meta programming for a generic & short solution

                              Template Parameters
                              TType of data to be forwarded
                              Parameters
                              valuedata to be forwarded
                              Returns
                              Reference to the CopyStream object allowing concatenation of operators
                              template<typename T >
                              CopyStream& CopyStream::operator<< ( T &(*)(T &)  f)
                              inline

                              Deal with [OutputStream] manipulator functions.

                              Template Parameters
                              TManipulator type
                              Parameters
                              fpointer to manipulator function
                              Returns
                              Reference to the CopyStream object allowing concatenation of operators
