* A renderer that makes it quick and easy to create customized forms.

* custom-looking forms, the ability to separate the creation of form
* elements from their display, and being able to use QuickForm in
* widget-based template systems. See the online docs for more info.
* For a usage example see: docs/renderers/QuickHtml_example.php
