commit a79776cde676a6109f0c4e1d045d724285d298fb
Author: Gordon Ball <gordon at chronitis.net>
Date:   Sat Dec 17 16:46:56 2016 +0100

    Don't automatically import ipywidgets
    
    ipywidgets.find_static_assets() is a no-op for ipywidgets > 4, which instead
    use the nbextensions mechanism, but causes a warning to be shown if the
    (redundant) widgetsnbextension package is not installed
