Split Docs

[MartinuzziFrancesco]

At the moment the docs are referencing some methods and functions that have been moved to YAXArrays.jl.

The current documentation also documents ESDLPlots.jl and while it is useful it think a more clear distinction could be more helpful to those encountering the package for the first time.

I have started to tackle both issues locally and I will push a very basic PR in the next days to start the split.

Yes that is definitively needed. It would be great, when you could start this with a PR.
See also JuliaDataCubes/YAXArrays.jl#38. Feel free to add topics there that are missing in the documentation.

I can only second what @felixcremer said, thanks a lot for starting to help on fixing the very messy documentation

I believe this was addressed by #266
