/**
 * Creates a <a> link tag of the given name using a routed URL
 * based on the module/action passed as argument and the routing configuration.
 * 
 * If null is passed as a name, the link itself will become the name.
 * 
 * Examples:
 *  echo link_to('Homepage', 'default/index')
 *    => <a href="/">Homepage</a>
 *  
 *  echo link_to('News 2008/11', 'news/index?year=2008&month=11')
 *    => <a href="/news/2008/11">News 2008/11</a>
 *  
 *  echo link_to('News 2008/11 [absolute url]', 'news/index?year=2008&month=11', array('absolute'=>true))
 *    => <a href="http://myapp.example.com/news/2008/11">News 2008/11 [absolute url]</a>
 *  
 *  echo link_to('Absolute url', 'http://www.google.com')
 *    => <a href="http://www.google.com">Absolute url</a>
 *  
 *  echo link_to('Link with attributes', 'default/index', array('id'=>'my_link', 'class'=>'green-arrow'))
 *    => <a id="my_link" class="green-arrow" href="/">Link with attributes</a>
 *  
 *  echo link_to('<img src="x.gif" width="150" height="100" alt="[link with image]" />', 'default/index' )
 *    => <a href="/"><img src="x.gif" width="150" height="100" alt="[link with image]" /></a>
 *    
 * 
 * Options:
 *   'absolute'     - if set to true, the helper outputs an absolute URL
 *   'query_string' - to append a query string (starting by ?) to the routed url
 *   'anchor'       - to append an anchor (starting by #) to the routed url
 * 
 * @param  string  text appearing between the <a> tags
 * @param  string  'module/action' or '@rule' of the action, or an absolute url
 * @param  array   additional HTML compliant <a> tag parameters
 * @return string  XHTML compliant <a href> tag
 * @see url_for
