docs: Whether to add the children of given target to the list of target children
  to exclude from this transition. The <code>exclude</code> parameter specifies
  whether the target should be added to or removed from the excluded list.
  <p/>
  <p>Excluding targets is a general mechanism for allowing transitions to run on
  a view hierarchy while skipping target views that should not be part of
  the transition. For example, you may want to avoid animating children
  of a specific ListView or Spinner. Views can be excluded either by their
  id, or by their instance reference, or by the Class of that view
  (eg, {@link Spinner}).</p>
  
  @param target  The target to ignore when running this transition.
  @param exclude Whether to add the target to or remove the target from the
  current list of excluded targets.
