Document wombat js upstream

[mgautierfr]

https://github.com/webrecorder/wombat is a nice project and our solution is totally based on it.

However, there is no documentation on how it's working or how to configure it.
It would be nice to create this documentation and send a PR to improve wombat.

It's certainly very much needed! But do we (you) have enough info to make such a PR? See also webrecorder/wombat#129, where it seems there is an "all or nothing" approach to documentation.

@mgautierfr Can you please make an approach proposal?

Making all this documentation has been judged an overwhelming / not worth it effort for now.
We already have some comments in our codebase for what looks important.
Let's close this issue until we have something really specific needed.
