/**
* Returns a JavaScript snippet to be used on the AJAX callbacks for starting
* visual effects.
*
* Example:
* ScriptaculousHelper::visual_effect('highlight', 'posts',
* array('duration' => 0.5 ));
*
* If no '$element_id' is given, it assumes "element" which should be a local
* variable in the generated JavaScript execution context. This can be used
* for example with drop_receiving_element():
*
* ScriptaculousHelper::drop_receving_element(..., array(...
* 'loading' => ScriptaculousHelper::visual_effect('fade')));
*
* This would fade the element that was dropped on the drop receiving element.
*
* You can change the behaviour with various options, see
* http://script.aculo.us for more documentation.
