Microsoft CodeXGlue
#978 is working on adding code refinement

maybe we should keep the CodeXGlue benchmark (as glue) and don't merge the code_refinement dataset proposed in #978 ?

cc @reshinthadithyan Hi @madlag and @lhoestq , I am extremely interested in getting this dataset into HF's library as I research in this area a lot. I see that it hasn't been updated in a while, but it is very close to being finished. If no one is currently working on this, I'd be happy to do any final touches that might be needed to get this merged. Hi @ncoop57 ! Thanks for your interest and sorry for the inactivity on this PR.
Sure feel free to create another PR to continue this one ! This one was really close to being merged so I think it won't require that much changes. In addition to my previous comments, there should also be a "Contributions" subsection (see the template of the README [here](https://github.com/huggingface/datasets/blob/master/templates/README.md)) Superseded by https://github.com/huggingface/datasets/pull/2357 .
