docs: Makes grabbing the second value out of a collection of Pairs a bit easier, e.g.
  given an iterable over Pair.of(?, String) objects:
  
  <br>
  <code>
  ... = Iterables.transform(iterable, Pair.snd(String.class))
  </code>
  
  @param clazz The class type for b.
  @param <T1> Expected data type for {@link Pair#a}
  @param <T2> Expected data type for {@link Pair#b}
  @return A function that returns null or the second value of the Pair, which also may be null
