Initial version of a MathJax 3 (prerelease) extension.

Don't merge yet - this doesn't work yet.

I have pushed workarounds for mathjax/MathJax-src#68 and mathjax/MathJax-src#69. I suspect that neither of these are intended behavior.

This is still not quite working, as I have not figured out how to have webpack pick up the MathJax fonts in mathjax2/css. Ideas?

[jasongrout]

Latest commit seems to get things to render okay, but the font location is hardcoded, so it doesn't look that great. Since we can't directly influence the jlab webpack config, we can't put in the appropriate webpack redirections to handle the hardcoded fonts, so we'll have to wait on that one.

What made the setting of the document unnecessary?

[jasongrout]

I don't know. I just tried it again and it worked.

The fonts issue has had some work in MathJax, so I think it's ready to tackle getting the fonts to load again. See mathjax/MathJax-src#70 (comment)

@jasongrout This is now working, with the caveat that we need to update the JupyterLab webpack config to pick up .otf fonts, which is used in one of the typefaces.
Update: The webpack issue is now fixed in master (jupyterlab/jupyterlab#3500)

I am seeing some errors with the parsing of HTML, but I think those might be MathJax3 bugs.
cf. mathjax/MathJax-src#78

@jasongrout I've been keeping this more-or-less up to date. Now mathjax3 is in beta, and some of the rendering bugs we saw in earlier versions have been ironed out. I think this is probably ready to merge and publish.
