 /**
 * The CycleHelper is used to cycle through the provided strings. 
 * You can use it for example to set alternate classes for table rows.
 * Usage is simple: 
 * <code>
 *   <table> 
 *   <?php foreach($items as $item):?>
 *     <tr class="<?php echo $cycle->cycle("odd", "even");?>"">
 *       <td><?php echo $item;?></td>
 *     </tr>
 *   <?php endforeach;?>  
 * </code> 
 * 
 * This will create rows where the class alternates between "odd" and "even".
 * 
 * If you need more than one cycle you can use named cycles:
 * <code>
 *   <?php $items = array("Car" => array("VW", "Fiat", "Ford"), "Food" => array("Pizza", "Hotdog"), "..." => array("..."));?> 
 *   <table> 
 *   <?php foreach($items as $item => $aliases):?>
 *     <tr class="<?php echo $cycle->cycle("odd", "even");?>"">
 *       <td>
 *         <?php echo $item;?>: 
 * 	       <?php foreach($aliases as $alias):?>
 *           <div class="<?php echo $cycle->cycle("one", "two", "three", array("name" => "second_cycle"));?>">
 * 				<?php echo $alias;?>
 *           </div>
 *         <?php endforeach?>  
 *      </td>
 *     </tr>
 *   <?php endforeach;?>  
 *   </table>
 * </code>
