To have a potential with broad element coverage + support for B

I'll have a look at this. This is probably almost covered in some code I have access to.

I think the issue here is gathering references for Teter potential, most old papers only reference it as private communication. There is a huge database of Teter potentials similar to the Pedone one I had collected somewhere, I can share it with you if I find it.

Edit: I found it I'll share what I have by email.
