Protobuf documentation generator

[rmichela]

Raw proto files aren't the easiest to read.

Protoc-gen-doc looks like a great project for generating this documentation. It would be great if Protoc-gen-doc were integrated with Maven as a protobuf generator plugin.

Would https://github.com/pseudomuto/protoc-gen-doc be a good start?

Protoc-gen-doc looks fantastic and has come a long way since I last saw it.

It would be awesome if protoc-gen-doc were mavenized so it can easily work with the protobuf-maven-plugin. I've updated the issue description.
