/**
 * ClientScript class is an extension on Yii's CClientScript to register scripts inside a view. 
 * It keeps your code hightlighted and readable by your IDE.
 *
 *  I've modified the code to remove the script tags using a regular expression, because it may occur that other HTML tags are used within a JavaScript string. I also add a parameter for htmlOptions since this is available in the registerScript function. Finally I added some comments.
 *
 *  Usage:
 *  1. Save the file in your /proteced/components/ dir
 *  2. Add the classname to your config
 *
 *  return array(
 *      ...
 *      'components'=>array(
 *          'clientScript'=>array(
 *              'class'=>'ClientScript',
 *              ...
 *          ),
 *          ...
 *      ),
 *      ...
 *  );
 * 
 * Usage is simular to {@link CClientScript::registerScript}
 * The <script> tags are required for highlighting and IDE functionallity and will be removed automatically.
 * 
 * Example:
 * 
 * <?php $cs = Yii::app()->clientScript;
 * $cs->beginScript('my-first-script', CClientScript::POS_HEAD, array('charset'=>'UTF-8')); ?>
 * <script>
 * // Write your code here.
 * </script>
 * <?php $cs->endScript(); ?>
 * 
 * <?php $cs->beginScript('my-second-script'); ?>
 * <script type="text/javascript">
 * // Write your code here.
 * </script>
 * <?php $cs->endScript(); ?>
