[aaliomer]

I created a file interface for htsget incase you're using a file system instead of google cloud I didn't change the previous code and I didn't add documentation for it (pretty self explanatory)

We found a Contributor License Agreement for you (the sender of this pull request), but were unable to find agreements for all the commit author(s) or Co-authors. If you authored these, maybe you used a different email address in the git commits than was used to sign the CLA (login here to double check)? If these were authored by someone else, then they will need to sign a CLA as well, and confirm that they're okay with these being contributed to Google. In order to pass this check, please resolve this problem and have the pull request author add another comment and the bot will run again. If the bot doesn't comment, it means it doesn't think anything has changed.

Thanks for reaching out. I took a look and, after discussing it with our product manager (@sheffi), this doesn't look like it really aligns with our product roadmap.

This server is intended as an implementation of HTSGET on top of Google's Cloud technologies. A local file-based implementation isn't something that we are looking to add to this product at this time.

If you need this functionality for a project of your own and would like to use our server as a foundation, I suggest keeping your changes in a fork that can be used by other people with similar problems.

Thanks, Aaron
