That's a good idea. And as this is a well-defined, self-contained task,
I would suggest to do that work on a feature branch of its own, and as
soon as it's complete (including tests and perhaps even benchmarks),
submit a PR to the `develop` branch of the master repo.
Please also discuss with Miral & Mateusz as there are many more IP
algorithms that will be added over the next couple of months, and it
would be good to share a common directory structure as well as build &
Let's discuss details on gitter.
