Grpc chat-system

This is a simple console based chat system implemented with Grpc in Go. Grpc uses HTTP2 internally for fast connectivity. Grpc also
provides bi-directional streaming, which helps to stream data both ways.

• Build the Docker File provided. The docker will install the grpc and protoc dependencies and go modules

• Run the docker Image. In the docker instance command Prompt,

    *To Start the Server :  .\server_main
  
    *To Start the client :  .\client_main
    *To connect to server and start app :   c <ip_address>:12000
          *Once both client and server are up and running, User will have to give 0.0.0.0:12000 (any IP address and port must be 12000). This can be <br /> done using the following commands:<br />  
  

Once connected to server user will have to login by giving the following command.
-u <user_name>

j <group_name> :
 To join a group. If the given group doesn't exist, then a new group will be created and the user will be added to participants list.
If the user is already present in the group, then that user will be removed from the current group and will be added to the new group.

Now user can perform following actions after joined a group:
a <message_> :
  This command is used to append message to the chat.
l <message_number>:
 This command is used to like a message. Here message id is the number displayed before every message. A user can not like his own message.
r <message_number>:
 This command is used to dislike a message. A user can only unlike a message iff the user had liked the same message beforehand.
p
  This command prints all the messages right from the group creation with latest message on bottom and oldest message on top.
q
 This command can be used at anytime after runs the client. This command terminates the client session and also removes
all information related from the server storage.

Once after joining a group the user is shown with recent 10 chat messages of the group. User can use p command to see full chat history.
For every action performed by the user, all other active participants are broadcasted with the change.
