walks you through the construction of a simple client and server and introduces
various features of gRPC.
When you finish the tutorial, you will be able to
- Create a protobuf schema that defines a simple RPC service
- Create a Java server that implements the schema interface
- Create a Java client that accesses the server
- Create a Go client that accesses the Java server
- Update the service with advanced features like RPC streaming

# Step-0: define a service
This section presents an example of a simple service definition that receives
a message from a remote client. The message contains the users's name and
a message from a remote client. The message contains the user's name and
sends back a greeting to that person.
