[soft question] Partition of Unity based interpolation

Hi,
I'm interested in developing code for POU based interpolation of smooth functions (technically called Whitney extensions, in R^2 and R^3, C^2 for now because the algorithms become worse as more smoothness and dimensions are added). On the one hand, integrating it into Interpolations.jl could be interesting because more people may use it. On the other, these algorithms are still in a very early stage so the idea is to implement them more for experimental mathematics than actual applications.

I'm kinda new to the Julia community so I am debating between two options:

- Forking this repo and adding the functionality. I'm not totally against this option but there's a lot of machinery that would have to be added and some parts may be very different from BSplines.
- Creating my own repo, using Interpolations as a "base" structure and making my code consistent with Interpolations but a package in itself. This looks more reasonable to me as a non-expert in Julia.

I'm definitely tending towards the second option but I wanted to hear opinions from people here since it seems that it is an active repo with experts in Julia working on it. Any thoughts would be very appreciated!
