ator elements from the
  three iterators, the element in the result iterator is
  <code>Combine(X, Y, Z)</code>.</p>
 
  <p><code>zipwith3(fun(X, Y, Z) -&gt; {X, Y, Z} end, Iterator1, Iterator2, Iterator3)</code>
  is equivalent to <code>zip3(Iterator1, Iterator2, Iterator3)</code>.</p>
 
  Examples:
  <pre>  &gt; llists:to_list(
  &gt;  llists:zipwith3(
  &gt;   fun(X, Y, Z) -&gt; X + Y + Z end,
  &gt;   llists:seq(1, 3),
  &gt;   llists:seq(4, 6),
  &gt;   llists:seq(7, 9))).
