* Assemble HTML components (inserts html blocks in an html file) If no header.html and/or footer.html are provided, default to normal HTML closure. tl;dr; The tool should generate a valid html5 page regardless of footer and header. # Considerations * Page title, namely `<title>...</title>` should be derived from the first `<h1>` element content. Alternatively, using the AST from `comrak`, detect it. This would mean instead of returning the content from `md_to_html`, return a ```rust struct FileData { content: String, title: String } ```
