Convert JSON to ArchieML

[theproductiveprogrammer]

I had a use case for converting JSON to ArchieML. I've written an ArchieML generator and wanted to make it available to the ArchieML ecosystem. You can see the generator here:
https://www.npmjs.com/package/jughead

Would it make sense to add a pointer to it in the documentation or some reference somewhere?
