We are not placing any of these defs inside a package, because if you do the
resulting nanopb version is super verbose package mesh.
Protobuf build instructions:
* To build java classes for reading writing:
* protoc -I=. --java_out /tmp mesh.proto
To generate Nanopb c code:

* /home/kevinh/packages/nanopb-0.4.4-linux-x86/generator-bin/protoc --nanopb_out=/tmp -I=app/src/main/proto mesh.proto

Nanopb binaries available here:

* https://jpa.kapsi.fi/nanopb/download/ use nanopb 0.4.4
To lint:
* Install protolint: brew tap yoheimuta/protolint; brew install protolint
* Run it from the main directory: *protolint* lint .
* (optional) Have it fix the mundane warnings: *protolint* lint -fix .
* See https://github.com/yoheimuta/protolint for more info
