        "...like all things liquid - where there's a will, and ~36 hours to spare, there's usually a/some way" ~jaybe

        Usage:
            {% 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(es) for each list item; has support for '%level%' placeholder, which is the current heading level
            * submenu_class (string) :   ''   - add custom class(es) for each child group of headings; has support for '%level%' placeholder which is the current "submenu" heading level
            * base_url      (string) :   ''   - add a base url to the TOC links for when your TOC is on another page than the actual content
            * anchor_class  (string) :   ''   - add custom class(es) for each anchor element
            * skip_no_ids   (bool)   : false  - skip headers that do not have an `id` attribute

        Output:
            An ordered or unordered list representing the table of contents of a markdown block. This snippet will only
            generate the table of contents and will NOT output the markdown given to it
