Concepts related to p2p chat :

1. we should append \n for every message as we are using it as delimiting character while reading it.
   
2. S.close() used for closing stream.
   
3. once a stream is opened , the object of stream should be used again and again untill it is closed. thats why we use for loop to stay on same stream for chat.
   
4. In order to speak to other peer , our peer should add the multiaddress of first peer to its peer table.
