/** 
* Normalizes the input parameter to be a valid URL. 
* 
* If the input parameter is an empty string, the currently requested URL will be returned. 
* 
* If the input parameter is a non-empty string, it is treated as a valid URL and will 
* be returned without any change. 
* 
* If the input parameter is an array, it is treated as a controller route and a list of 
* GET parameters, and the {@link CController::createUrl} method will be invoked to 
* create a URL. In this case, the first array element refers to the controller route, 
* and the rest key-value pairs refer to the additional GET parameters for the URL. 
* For example, <code>array(&#39;post/list&#39;, &#39;page&#39;=>3)</code> may be used to generate the URL 
* <code>/index.php?r=post/list&page=3</code>. 
* 
* @param mixed $url the parameter to be used to generate a valid URL 
* @return string the normalized URL
