`ein:jupyterhub-connect' is now interactive and will query for url, user, and
password before trying to authenticate in Jupyterhub and start a server for the
user.
We can do all of these through the function `ein:jupyterhub-connect'. Everything
works great until we actually try to access the running notebook server at which
point the hub redirects us to the login page. I've bumped to the mailing list,
we will see if anyone there can help.
`ein:jupyterhub-connect' will take a url for the jupyterhub server, a user, and
a password and then get and store the authorization token for that user.
Big things on the way!
Per popular request, publishing what I have so far for jupyterhub support, which
is not much. But it may server as a starting point for someone smarter than I.
