 * A <Section> gets a `path` and optional children. If it has children it will
 * render those and prepend each child's `href` prop with the provided `path`.
 * This means that you can do:
 *
 * ```jsx
 * <Section path="/section">
 *   <Link href="foo">Links to /section/foo</Link>
 * </Section>
 * ```
 *
 * If no children are provided, it renders a <NavList> with the provided
 * `path`.
