/**
* Core of a network server. This class is distinct from a ServerSocket in
* that a ServerSocket is one listening socket, nothing more. Socket will
* manage a pool of both ServerSockets and connected Sockets along with
* their protocols and buffers.
*
* To start serving on a new port, use the addPort functions. Each call to
* addPort creates a new ServerSocket, starts it listening, and adds it to
* the server pool.
*
* All of the real work is done by scan, which will wait for up
* to the timeout set by setTimeout before returning if there is no data
* pending. scan should probably be called in some sort of tight
* loop, possibly in it's own thread, or in the main control loop.
*
* In order to use a Server you must subclass it and implement the pure
* virtual functions. These allow you to receive notification of events
* happening within the server itself, and actually makes it useful.
