Chameleon JupyterHub Appliance

[JupyterHub](https://jupyter.org/hub) is a multi-user Jupyter Notebook environment that allows easy management of multiple Notebook servers. You can install this application on a node reserved by Chameleon to allow you to take advantage of additional resources, e.g. a private experiment network you provide or accelerator devices such as GPUs. This appliance is exposed over the public internet via a TLS-secured endpoint and supports other users logging in with their Chameleon credentials, so you can choose to share the server with other collaborators if you wish.
