gRPC/

The Math gRPC module

• math/math/math.proto file holds the prototype buffer language code which structures our protocol buffer data.
• math/math/math.pb.go file is created using protocol buffer compiler with file types and API functions.
• math/server/server.go file executes the server which accepts a Request message and sends a Response message.
• math/client/client.go file executes the client which sends a Request messasge to server and prints the incoming response.
