  JavaScript port of John Gruber's TitleCase Perl script:
  http://daringfireball.net/projects/titlecase/TitleCase.pl

  This filter changes all words to Title Caps, and attempts to be clever
  about *un*capitalizing small words like a/an/the in the input.

  The list of "small words" which are not capped comes from
  the New York Times Manual of Style, plus 'vs' and 'v'.
