Non-JS Doc Metadata

[coreybutler]

Metadoc is great for producing API metadata, but there is currently nothing for generating guides. Guides are almost always static HTML sites (not just a page). It's possible to identify the structure of an individual document by it's headings (like the <h1> tag), but there isn't much for producing a master index/table of contents.

Metadoc should be capable of producing indexes that can be used to generate a table of contents for a guide.

This may require some inspection of directory/folder structures to determine things like chapters, subchapters, or other types of volumes. Metadoc may also need to parse the markdown/HTML content for comments to assist with this. Finally, it should be capable of verifying links between documents.
