Currently there's directories like "output-dir" in the result zips; they should not be there.
when downloading a single output, there should be no top-level directory named after the option
when downloading all outputs ("download all results" button), then all outputs should be merged into one directory
if there are file naming conflicts so that the directories cannot be merged; then separate top-level directories will be created based on the names of the options. Possibly using the nicenames of the options if they are valid filenames.
