Hi @eeshan9815  
if you or @dpsanders feel motivated to implement topological (Lefshetz) index computation (see e.g. the discussion in [here](https://discourse.julialang.org/t/ann-intervalrootfinding-jl-for-finding-all-roots-of-a-multivariate-function/9515)) in IntervalRootFinding, feel free to ask me any questions.

This is really less complicated than it sounds (no need to chase commutative diagrams; just count roots with “topological multiplicity”, which is the sign of the determinant of the jacobian; the only tricky part is computing the multiplicity for maybe-roots with maybe-non-invertible jacobian)

But I’m not familiar with the codebase, am not an active user of the JuliaIntervals world, and do not plan to implement this myself in the near future. I am working on some other computational topology stuff though, so there might be overlap.

Otherwise, welcome and have a nice summer!
