    "...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

    Output:
        An 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
