Neat! Two questions:

1. have you considered the MIT license instead of GPL (I will not rehash discussions about these, eg [this topic](https://discourse.julialang.org/t/gpl-and-virality/7715)),

2. the codebase implements a lot of nonlinear solution methods that are generic and could be useful outside this package, have you considered factoring these out to their own package, or contributing to existing ones?
