This is the method that will place the anchor tag and id of the
 footnote within the paragraph body itself.

 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.
