Full disclosure: I am one of the authors of this work.

There was some interest in my other research, LittleD (https://news.ycombinator.com/item?id=10621337), and IonDB has been another focus for a few years in the lab I work in. I thought IonDB might be interesting to this community as well.

Again, feel free to ask questions.

I would suggest renaming the IONIZE, NEUTRALIZE functions (macros?) to something more boring but descriptive like wrap_key, unwrap_key.

The funny thing is I was about to reply to you on the LittleD thread to tell you about this. Then... I saw the submitters name. Nevermind lol.
