Output to SVG file

[TheLostLambda]

Connected to me wanting to fix the small graphical bug in #63 , is it possible to add an option for exporting to an SVG file that can be edited in a vector graphics program? When trying to copy-paste the SVG from the HTML in the past, I think I ran into issues with undefined link references?

I don't recall exactly if that was the only issue, but perhaps removing links for the SVG output would fix things and make it easy to post-process these diagrams in an image editing program!

I'm thinking primarily the export of the overview diagram, but perhaps it would be useful to have a way to export all of the sub-component diagrams as well!
