/**
 * CPradoViewRenderer implements a view renderer that allows users to use a template syntax similar to PRADO templates.
 *
 * To use CPradoViewRenderer, configure it as an application component named "viewRenderer" in the application configuration:
 * <pre>
 * array(
 *     'components'=>array(
 *         ......
 *         'viewRenderer'=>array(
 *             'class'=>'CPradoViewRenderer',
 *         ),
 *     ),
 * )
 * </pre>
 *
 * CPradoViewRenderer allows you to write view files with the following syntax:
 * <pre>
 * // PHP tags:
 * <%= expression %>
 * // <?php echo expression ?>
 * <% statement %>
 * // <?php statement ?></li>
 *
 * // component tags:
 * <com:WigetClass name1="value1" name2='value2' name3={value3} >
 * // <?php $this->beginWidget('WigetClass',
 * // array('name1'=>"value1", 'name2'=>'value2', 'name3'=>value3)); ?>
 * </com:WigetClass >
 * // <?php $this->endWidget('WigetClass'); ?>
 * <com:WigetClass name1="value1" name2='value2' name3={value3} />
 * // <?php $this->widget('WigetClass',
 * // array('name1'=>"value1", 'name2'=>'value2', 'name3'=>value3)); ?>
 *
 * // cache tags:
 * <cache:fragmentID name1="value1" name2='value2' name3={value3} >
 * // <?php if($this->beginCache('fragmentID',
 * // array('name1'=>"value1", 'name2'=>'value2', 'name3'=>value3))): ?>
 * </cache:fragmentID >
 * // <?php $this->endCache('fragmentID'); endif; ?>
 *
 * // clip tags:
 * <clip:clipID >
 * // <?php $this->beginClip('clipID'); ?>
 * </clip:clipID >
 * // <?php $this->endClip('clipID'); ?>
 *
 * // comment tags:
 * 
 * // the whole tag will be stripped off
 * </pre>
