Decouple the widgets from the Notebook.

[jdfreder]

Decoupling the widgets from the Notebook should make it easier for people to embed the widgets in their own non-notebook environment. For example, @rgbkrk has already expressed interest in doing this with his BitJet widget and Sidecar app.

This means splitting the WidgetManager into a WidgetManager or WidgetManagerBase (depending on whether or not it can be used without being inherited) and a NotebookWidgetManager.

We also may want to think about the installation a little more carefully, which we will have to do soon anyways. Users may want to install (A) for use with the notebook (B) for standalone use. If @SylvainCorlay 's proposal for kernel resource/extensions is implemented, (A) is instead to a specific kernel, not the notebook.

👍 to kernel resource extensions and this overall issue

This probably also means allowing Spyder to have a display area that could have widgets.

One nice possibility on the frontend might be making widgets as Web Components (perhaps with Polymer). That would allow them to be implemented/styled/etc in a way that is sandboxed from the rest of the page.

IIRC, Escher, the IJulia widget system, uses webcomponents and polymer a lot: https://shashi.github.io/Escher.jl/ (see also https://groups.google.com/forum/#!topic/julia-users/UEaYPlBuIkc for a brief description of how it works)

I am going to looking into webcomponents - I think it could be useful for
us...

@willwhitney thanks! I think that's a good idea.

I think web components is finally maturing enough to start looking at it. When I looked at it several years ago for the sage cell server, it wasn't mature enough/supported in browsers enough.
