Client/Server application for dynamic text communication.

Task:

• client and server has to start communication via port 7300.
• server can request to change communication port in any time.
• client also can request to change communication port in any time.

Ex: Communication established via port 7300.

• Text messages can go in both directions.
• To change communication port client or server has to send message "NewPort-"
• Client or server has to replay "success" or "failure"
• In case of success communication will be re-established via New port

WAS NOT IMPLEMENTED:
Bonus option: communication port must be changed each 45 seconds without user disturbing.

How to build project:
server side:

1. cd server/
2. Run cmake .
3. run make

client side:

1. cd client/
2. Run cmake .
3. Run make

Work with server/client:

1. To start server/client run ./server <port_number>
   E.g: ./server 7300
   E.g: ./client 7300
   Note: client always sends messages to server first.
2. To change port enter on either side NewPort-<port_number> command.
   Note: port number must be numberical value in range from 1024 to 49151.
3. To stop either side enter Stop command.
   Note: If client disconnected, server will keep listening to new connections. If server disconnected, client will also stop working.
   Note: You cannot send Stop command on server if it doesn't have any active client connections.
   Note: Clinet can recconect with relevant server port executing ./client <port_number>
