""" Connect via ssh to a remote jupyter kernel
1. Start a jupyter kernel on the remote machine: 
    `(remote)$ jupyter kernel`
2. Note the kernel connection file location and copy to local machine (can use globbing if you escape, e.g. "\*"):
    `(local)$ scp remote-user@remote-host:<conn-file.json> .`
3. Use this script to quickly forward the appropriate ports over SSH:
    `(local)$ for port in $(python qt_connect.py <conn-file.json>); do ssh -f -N -L $port\:localhost:$port pi@192.168.1.90; done` 
4. Open a local qtconsole instance specifying a connection to the remote
kernel:
    `(local)$ jupyter qtconsole --existing <conn-file.json>`
