Embedding the widget in documentation

[llambourne]

Hi,

Thanks for making this widget! The widget works great in a notebook for me. However I'd like to use it to embed a network in a notebook, converted to html, and published online, and this does not work at the moment because (I think) where the ipywidget looks for the webpack bundle at unpkg.com/cytoscape-jupyter-widget it doesn't exist:

Failed to load resource: 
unpkg.com/cytoscape-jupyter-widget@%5E0.1.0/dist/index.js:1
the server responded with a status of 404 ()

Best,
Luke
