Refactor gridspacedesc.yml so all the subset info is standard and built in, and not user supplied

No description provided.

probably it should be in GGDUtils

How about I move default gridspecdesc.yml to src and make it a default argument. That way we can easily change defaults in future and it will leave the possibility open of supplying user-specified description.

[eldond]

That would solve the immediate issue. I wonder if maybe the subset definitions should be in a separate file, which would make them easier to find (if the file were subsets.yml) and also I think the use case for changing subsets is different from changing the other setup that's in that file.

But even if you don't want to split, what you say seems fine.

I did not go ahead with file splitting, partially because I could not understand what you meant. Creating 25 extra files for subset just to hold tiny amounts of meta data seemed too much to me, but maybe I misunderstood what you meant. I've opened two PRs that will resolve this issue as per the suggested changes above:

ProjectTorreyPines/SOLPS2imas.jl#24
#41

@anchal-physics No, not 25 files. Just two. One for the space and index stuff, and one for all of the subsets. Well, actually three might be better:

1. space and index (because I think it's allowed to load one IDS file with a bunch of ggd_idx instances for holding different things)
   • The reason this is a different file is because there's a use case for the end user to customize it, and it's very short and therefore edits are tractable (if the subsets are taken out).
2. standard subsets (all the ones from the docs)
   • The reason this is a different file is that its source is all just GGD documentation
   • This file would be updated if the makers of GGD changed the standard indices
3. extended subsets (all the ones we added with negative indices)
   • The reason this is a different file is that its source is all just us making stuff up
   • This file would be updated if we made up new extended subsets

Aah, I got it now. I'll request new PRs in the future bringing this feature. We can leave this issue open to signify remaining work.
