Generate documentation for Bess

As opposed to the official documentation, this program generates documentation that

• lists every class method (dedicated protobuf message is not a requirement)

• links c++ defintions and usage examples.

Execution steps

1. Clone or update bess repository,
2. Compile bess with container_build,
3. Extract documentation from protobuf messages,
4. Collect modules and their methods by running bessd in a container,
5. Find method definitions by running gdb,
6. Write a dummy module (globals.py).

Uninstall

To remove the software, you also need to remove some docker images.

$ docker image rm gen-bess-doc-globals
$ docker image rm nefelinetworks/bess_build:latest-git
$ docker image rm nefelinetworks/bess_build
$ docker image rm pseudomuto/protoc-gen-doc

Is it any good?

At least the bess language server uses it.
