Demo project demonstrates client server communication using GRPC and protocol buffers

Steps to run:

1. Import grpc-client and grpc-server applications separately.
2. Add a cert.pm and key.pm (certificates file) under resources folder in both the projects. https://stackoverflow.com/questions/10175812/how-to-create-a-self-signed-certificate-with-openssl
3. Pass any value between 1 to 4 as command line arg in client application, based on that it invokes different apis.

To compile message definition in client side (proto file) use below command (change similarly for server app)

protoc -I .\grpc-client-java --java_out .\grpc-client-java\src\main\java .\grpc-client-java\messages.proto --grpc_out .\grpc-client-java\src\main\java --plugin=protoc-gen-grpc=.\grpc-client-java\lib\protoc-gen-grpc-java-1.0.1-windows-x86_64.exe

To run the above you need to download protoc-gen-grpc-java-1.0.1-windows-x86_64.exe and put that in lib folder.
