Very nice!

Is the repository open now?  I have a couple of small changes to the
bessel functions to correct an issue where the bessel functions
weren't being numerically evaluated, and a minor enhancement to allow
bessel_j to be computed for negative orders.

There are other numerical evaluation deficiencies there, but I haven't
fixed those yet.

I'd also like to unify (maybe) the issue of bessel_j and %j in the
code.  I think we agreed that all uses of %j should become bessel_j.
