IPyWidgets on standalone webpage + electron

[nmearl]

This PR demonstrates rendering ipywidgets on a standalone webpage as well as embedded in an electron app.

Currently, there are issues with displaying bqplot widgets -- this has to do with the custom jupyter-astroimage buried within the installation that is not registered with the node package manager on installation. The jupyter-astroimage package is not available on the npm registry and so currently is not identified when rendering on the page.

Currently attempting to work around this issue by manually linking the package as a local dependency.

The bqplot stuff is super important for all this. Do you think you will get it working today?

I'm actually having the same issues trying to get any bqplot stuff or widget to display in the web page. I get a bunch of errors regarding rendering children elements. I even tried stripping it down to a barebones HBox widget and couldn't get it working.

[nmearl]

It's no longer an issue with bqplot, as I can display a raw bqplot just fine. I think it has to do with the glue implementation and its use in your cubeviz hack.

[havok2063]

I still have issues with the standard bqplot. I pulled your most recent changes and this is what I see. The console indicates issues with container heights.

This is a css issue. Try with the latest push.

Could you rebase? I was just going to ck it, but I think it is behind a bit.

[nmearl]

Everything shows that it's up-to-date with master. Could you also give me write access to this repo?

[brechmos-stsci]

@eteq could you give Nick access? I don't believe I have the ability to give access to others (no Settings).

@brechmos-stsci Since we already have several devs able to successfully install and run the web/desktop app, I think it's best to have you review based on your experience with the raw install instructions. I'd encourage you to write down the specific issues you're having here as well as the results of any extra debugging instructions.

@nmearl is this branch ready for merge? I believe one person has already installed and run this... I can still go through and do a test install.

[nmearl]

This is ready for merging. Cami was successfully able to install and run the web app and electron app locally. @javerbukh intended to attempt to install as well in an effort to review the PR. If Cami is sufficient, this can be merged now.
