  Make table of contents a float and aligned to the right.
  This is similar to wikipedia.  The alternative breaks up the
  flow of text and leads to people ignoring the first section.

  In some cases, like the FAQ, we do want the TOC to be inline
  and not a float, so make a style that "undoes" the change above.
  Then use it like "<div class="tocinline">__TOC__</div>"

  This "magic" CSS means toc id inside tocinline will not float.
