Export test_module

[timcdlucas]

The BuildModule workflow is kind of odd when combined with git (makes sense when submitting modules by online form). You keep a separate script with your function, write docs into BuildModule arguments and write into the modules repo. Or something. But instead, keep git history within the modules repo and doing zoon:::check_module('my_module.R') makes perfect sense.

Is there anything I'm missing or can we just fully document and export this function?
