#430 section editing within .tex files

[Lee Worden]

Wouldn't that be nice?

Bringing over from [[Talk:WorkingWiki]]:

Associating parts of the HTML output back to the various source files. This would allow a sort of section-editing feature (e.g. this part of the document came from methods.tex - click here to edit that), and would allow displaying the Methods section on the methods.tex page.
