Compress and download folder

[hadim]

The goal of this PR is to integrate https://github.com/hadim/jupyter-archive to Jupyter.

Two others to JLab and jupyter_server will also be submitted.

For now, there is nothing in this commit because I need some guidance on how to integrate the Python code into the notebook.

My idea was to create a class called ArchiveHandler next to FilesHandler in files/handlers.py but it appears that FilesHandler.get is never called when downloading a file from notebook or Jlab.

Instead web.StaticFileHandler is used base.handlers.AuthenticatedFileHandler.get.

Two questions:

• What is the point of FilesHandler then?
• Where should I implement ArchiveHandler? The code is here: https://github.com/hadim/jupyter-archive/blob/master/jupyter_archive/handlers.py#L45

I am not sure I have implemented the way you guys want but this PR + the JLab PR is fully working.

Thanks, @hadim. Sorry for the long delay! This is fantastic work! Thank you for submitting the PR here with this significant amount of work.

Unfortunately, Jupyter Notebook is not really under active development anymore (see this section of the README). We're focusing on maintaining the current codebase and accepting PRs with security fixes for now.

Given the current state of the notebook repo, I would suggest we move the server-side piece of this work to Jupyter Server and discuss there. If it lands in Jupyter Server, we can help get it integrated to jupyterlab.

In the meantime, I'm going to close this PR here.
