 * Eina Iterator examples.

 * These examples demonstrate how to work with eina_iterator methods.
 * Both an eina_list and an eina_array are created and an iterator obtained
 * for both. You can see how we can use iterators irrespective of the source
 * and also that there are different ways to work with iterating content.
