 * tocName (default: "toc") - the key name which is attached into vfile.data
 * tocRef (default: []) — another way of exposing the tocItems
 * maxDepth (default: 6) — max heading depth to include in the table of contents; this is inclusive: when set to 3, level three headings are included
 * skipLevels (default: [1]) — disallowed heading levels, by default the article h1 is not expected to be in the TOC
 * includeParents — allow headings to be children of certain nodes; internally uses unist-util-is Test
 * skipParents (default: []) — disallow headings to be children of certain nodes; internally uses unist-util-is Test
 * exclude — headings to skip, wrapped in new RegExp('^(' + value + ')$', 'i'); any heading matching this expression will not be present in the table of contents
 * prefix - the text that will be attached to headings as prefix, like "text-prefix-"
 * after — heading to look for, wrapped in new RegExp('^(' + value + ')$', 'i'); the TOC items will be generated after that heading section
 * callback - It is a callback function to take the array of toc items as an argument
