https://github.com/allejo/jekyll-toc
"...like all things liquid - where there's a will, and ~36 hours to spare, there's usually a/some way" ~jaybe

{% include toc.html html=content sanitize=true class="inline_toc" id="my_toc" h_min=2 h_max=3 %}
Parameters:
* html (string) - the HTML of compiled markdown generated by kramdown in Jekyll
Optional Parameters:
* sanitize (bool) : false - when set to true, the headers will be stripped of any HTML in the TOC
* class (string) : '' - a CSS class assigned to the TOC
* id (string) : '' - an ID to assigned to the TOC
* h_min (int) : 1 - the minimum TOC header level to use; any header lower than this value will be ignored
* h_max (int) : 6 - the maximum TOC header level to use; any header greater than this value will be ignored
* ordered (bool) : false - when set to true, an ordered list will be outputted instead of an unordered list
* item_class (string) : '' - add custom class for each list item; has support for '%level%' placeholder, which is the current heading level
* baseurl (string) : '' - add a base url to the TOC links for when your TOC is on another page than the actual content
