Zenodo DOI?

Hi there,

I'm a PhD student in the group of Hans Fangohr, and I used this material to learn the concepts behind the Barnes-Hut method/FMM. I'd like to cite the repository in a paper that I'm writing - is there any chance the authors could put the repository onto Zenodo so I can cite the DOI?

Also wanted to say thanks; I found the material very instructive.

All the best,
Ryan
