gRPC C++ API

The gRPC C++ API mainly consists of the following classes:

• grpc::Channel, which represents the connection to an endpoint. See the gRPC Concepts page for more details. Channels are created by the factory function grpc::CreateChannel.
• grpc::CompletionQueue, the producer-consumer queue used for all asynchronous communication with the gRPC runtime.
• grpc::ClientContext and grpc::ServerContext, where optional configuration for an RPC can be set, such as setting custom metadata to be conveyed to the peer, compression settings, authentication, etc.
• grpc::Server, representing a gRPC server, created by grpc::ServerBuilder.

Refer to the examples for code putting these pieces into play.
