gRPC broadcast example with BiDirectional streaming RPCs

Usage

First, run server/server.go then gRPC server listening on 0.0.0.0:50051.

$ go run server/server.go

Next run client/client.go with argument (client's name).

For example if you run 2 clients named 'Alice' and 'Bob', you will get the following output:

$ go run client/client.go Alice

$ go run client/client.go Bob
