def footnote_html(id, time)

      footnote_content = sequence.elements.map { |s| s.html }.join

This is the method that will actually spit out the div that the
 footnote's content is in. This will generally be called after all of the
 paragraph's text has been spit out so that the footnotes can be appended
 after. Note that it needs to be passed an id from the caller so that it
 can be linked to corretly with an anchor tag in the body of the main text.

 I'm passing in a time variable here to make links unique. You see,
 if you parse many of these entries on a single HTML page you'll end up
 with multiple #footnote1 divs. To make them unique, we'll pass down
 a time variable from above to seed them.
