For backup and reproducibility, we should probably have a function that downloads the files.
rdt = RdtClient ...
rdt.listArtifacts
loop to download each of them
compress the folder
Put it somewhere when you publish a paper.
Do we ignore subfolders? Or ... recursively? Or take a list of subfolders ...
This seems useful when we publish a paper that needs the files and we want to put the data on a permanent repository (e.g., the stanford digital repository). Then if the AWS site goes away, we still have the files available.
Probably other uses, too.
