ragavi integration

[o-smirnov]

Need to integrate ragavi into padre properly, in terms of:

• adding to requirements.txt

• sorting out nodejs virtualenv issues. Nodejs is needed by JS9 anyway, so it ought to be installed for both consistently.

• sorting out image export from ragavi. Currently it's asking for selenium, then once that's pip installed, I get a RuntimeError: PhantomJS is not present in PATH.

I think this issue, as originally conceived, has been made largely irrelevant by the combination of HTML output in ragavi, plus HTML thumbnail rendering in radiopadre.

There is one lingering problem that deserves a look: #92 (comment)

Another way to address this @Mulan-94, maybe ragavi could be asked to generate a static preview.png file alongside the HTML plot? Radiopadre could then be tweaked to say hey, if I see foo.html and foo.html.preview.png together, then I don't need to render a thumbnail for the HTML, I can just use the supplied image directly.

@o-smirnov , what do you think of this solution?

[o-smirnov]

Which solution exactly? There's a lot of stuff on that page...

You're currently generating a standalone HTML document as per the first subsection, correct?

[Mulan-94]

Yes sorry, I mean generating HTML components that can be embedded in other HTML documents.

[o-smirnov]

Ah, that's way more integrated than I was thinking. I like the standalone HTML fine for now, it's nice and standard and compatible with everything. I was just wondering if you can't export to PNG at the same time?

It can be done with some additional set up ... I'll check how best this can be achieved smoothly
