The code required for the client program is exactly that which was employed in
the TCPEchoClient program from the last chapter. However, since (i) there was only
a modest amount of code in the run method for that program, (ii) we should avoid
confusion with the run method of the Thread class and (iii) it'll make a change (!)
without being harmful, all the executable code has been placed inside main in the
MultiEchoClient program below.
