 * An iterator over {@link Position} instances, that is wrapped around
 * another 'parent' {@link Iterator}. The parent can be either another
 * {@code PositionIterator}, or an iterator over {@link KnuthElement}s,
 * for example.<br>
 * The {@link #next()} method always returns a {@link Position}. The
 * {@link #getPos(Object)} method can be overridden in subclasses
 * to take care of obtaining the {@link LayoutManager} or {@link Position}
 * from the object returned by the parent iterator's {@code next()} method.
