Resources for JupyterHub and nbgrader

This is meant to be a singular repository for resources related to running and updating JupyterHub with the nbgrader extension.

Right now, it doesn't contain a whole lot, but it does have scripts that serve as useful templates for migrating an existing JupyterHub deployment to a new course (e.g. a new semester).

What it does

• Updates the current Anaconda environment, and specifically the JupyterHub and nbgrader applications.
• Creates the system users needed and configures them with the nbgrader extension.
• Deletes previous users (and their home directories) on the system.

What it doesn't do (yet)

• Modify the nbgrader_config.py file in any way.
• Modify the jupyterhub_config.py file in any way.
• Create, delete, or otherwise edit any nbgrader courses.
• Use GitHub authentication.

Pull requests are welcome, as are any links to JupyterHub / nbgrader integration resources. Getting these two to play nicely together is a messy process; I'm hoping this will help clean it up a bit!
