Add a Root Page to the Exported HTML Page
Current Issue
docc2html currently doesn't produce an index.html file at the root of the exported folder that links to the generated HTML files documenting a target.
When publishing the documentation as an HTML page, you need to generate an HTML page that links to the targets or automatically forwards to a target if only one target is present.
You can see the issue in the following GitHub Pages based deployment: https://apodini.github.io/Template-Repository/ returns a 404 error. The DocC documentation is successfully found in the subfolders of the HTML export: https://apodini.github.io/Template-Repository/documentation/apodinitemplate/apodinitemplate/index.html
Suggested Solution
It would be great if docc2html could generate an index.html page listing all targets included in the exported documentation and linking to the related index.html pages in the subfolders.
If there is only one exported target, the page should automatically link to the only target present in the documentation archive.
