-Work is very much in progress, but and help is always welcome. If you want to help out but don't know where to start, take a look at issue [#5 - our feature wishlist](https://github.com/tlycken/Interpolations.jl/issues/5) =) There is also some [developer documentation](doc/devdocs.md) that may help you understand how things work internally.
