Simple example of a basic protobuf repository made for a Medium article. The goal is to showcase usage of well-known types in the same way Google does.
The Makefile has a single target called protobufs which generates go code
using shares types.
Transpiled go source files are stored in the _build folder. Notice how both
kennel/index.pb.go and notifier/index.pb.go reference ptypes/index.pb.go
and how the package they import reflects the path defined with go_package.
