 * This is a utility class providing a reader/writer capability required
 * by the weatherTelnet, rexec, rshell, and rlogin example programs.
 * The only point of the class is to hold the static method readWrite
 * which spawns a reader thread and a writer thread.  The reader thread
 * reads from a local input source (presumably stdin) and writes the
 * data to a remote output destination.  The writer thread reads from
 * a remote input source and writes to a local output destination.
 * The threads terminate when the remote input source closes.
