## Description
Modification to TCPExample4 to show the Message of the day (MOTD), depending on the day of the week.
The server side sets up a server listening for incoming connectios.
When a client attempts a connection to the server it sends the day of the week for the current connection.
Once received the day of the week, the server reply with a message according to the day of the week.
