Design to replace vertical tabs on widgets page

[SylvainCorlay]

We are going to have a couple of new examples in the widgets gallery soon

• the matplotlib widget (jupyter-matplolib)
• nglview
• probably the molecular design toolkit.

The current vertical tabs are not great from the user experience's perspective.

Besides, for the widgets to benefit from the resize events, we should probably use a phosphor panel instead of pure css layout.

Since it will become a requirement for us to start using a phosphor widget in place of the current tabs for the widgets gallery, it could be really interesting work on design ideas for such a gallery.

Besides bqplot, pythreejs, ipyleaflet, we will also probably have items with nglview and the autodesk molecular design toolkit, and then ipympl when matplotlib 2.0 is released. I was thinking of a form of carousel with a small image for each library and then a classical document layout for each widget.

@SylvainCorlay Where do we stand with this? I can help out on this page if we wanted to start iterating!
