demonstrates how to use grpc to write a server that talks to an external server written in another language

implements Prof.Yair Sovran's design idea to create a candidate_server, which takes client request and answers in an evasive way.

(*candidate server talks to an external campaign_manager server to get retorted answer, incorporates it to form the final answer)

$ protoc -I . --python_out=. --grpc_out=. --plugin=protoc-gen-grpc=`which grpc_python_plugin` debate.proto

    this is running on local host port 80000

$ python candidate_server.py

$ chmod +x moderator.py 

$ ./moderator.py elaborate finance 2 3 1

$ ./moderator.py answer "what is your campaign budget" 5
