Initial checkin of gRPC to third_party/

third_party/grpc/examples/README.md

+# Examples
+
+This directory contains code examples for all the C-based gRPC implementations: C++, Node.js, Python, Ruby, Objective-C, PHP, and C#. You can find examples and instructions specific to your
+favourite language in the relevant subdirectory.
+
+Examples for Go and Java gRPC live in their own repositories:
+
+* [Java](https://github.com/grpc/grpc-java/tree/master/examples)
+* [Android Java](https://github.com/grpc/grpc-java/tree/master/examples/android)
+* [Go](https://github.com/grpc/grpc-go/tree/master/examples)
+
+For more comprehensive documentation, including an [overview](http://www.grpc.io/docs/) and tutorials that use this example code, visit [grpc.io](http://www.grpc.io/docs/).
+
+## Quick start

+Each example directory has quick start instructions for the appropriate language, including installation instructions and how to run our simplest Hello World example:
+
+* [C++](cpp)
+* [Ruby](ruby)
+* [Node.js](node)
+* [Python](python/helloworld)
