  The Server class defines a singleton representation of a internet server.
  It defines the traditional non-blocking select() server.

  \notes
  No reason why this should be a singleton as long as different
  ports are served.

  \todo
  Make Server an abstract class overriding its Run method to illustrate
  different network designs as well as different kinds of servers,
  e.g. httpd, ftpd, and telnetd.
