View Helper Case Notes
This is how it works:
views/helpers/MyHelper.php contains class Zend_View_Helper_MyHelper which has a function called myHelper()
Also, if you add a function called setView() to your class, then the View will pass you an instance of itself before it calls your view helper function.
public function setView($view)
$this->_view = $view;
public function myHelper($myVar)
