+ Chat  Server
+ 
+ A simple server that distributes any incoming messages to all
+ connected clients.  To use telnet to  your device's IP address and type.
+ You can see the client's input in the serial monitor as well.
+ Using an Arduino Wiznet Ethernet shield. 
+ 
+ Circuit:
+ * Ethernet shield attached to pins 10, 11, 12, 13
+ * Analog inputs attached to pins A0 through A5 (optional)
