@jnytra If you can, would you mind looking through this tutorial/example and letting me know if anything is unclear or doesn't make sense?

This is absolutely amazing. This is exactly what I needed to write a new adaptor. I don't have any comments yet, but I plan to write a new adaptor according to this tutorial, so I'll see.

@jnytra Sounds good! If you're planning to add any new adaptors or algorithms please file an issue first (I'll mark it as an enhancement and assign you to "fix" it) so that we don't end up working on the same thing :)
