MarkdownDocs default theme
This is MarkdownDoc's default theme which means this is the theme that will be used when running MarkdownDoc without a custom theme.
Because this is likely to be the most used theme of all, it is not as simple as a theme can get. For instance, there is quite a bit of logic in both index.js and the Swig templates. Fortunately, you don't have to deal with that at all.
