This is made using socket programming in python. Server and client can send and 
reveive messages from each other.

-> Allowing communication with trusted client only, check using first received 
   message from client as key message
-> Multithreading to handle multiple clients
-> Use of pickel to serialize any type of data
-> Handling of variable length data by passing payload size along with payload
-> Passing data identifier with payload as additional information to take specific
   action accordingly (eg. if data identifier is image then save payload as image)
-> Using keyboard interrupt to close client and server cleanly

1. Server.py
	(Note the Server IP)
	Enter the Port Number for the communication to Start  
	
	python3 server.py

2. Client.py
		
	python3 client.py 
	
	(Enter the port as entered in Server and IP of the Server)
