/**
* A stub renderer to use with HTML_QuickForm2 when actual form output is done manually
*
* The rendering step is mandatory if the form uses client-side validation
* or contains Javascript-backed elements. Using Array or Default renderer
* will add unnecessary overhead if such a form will later be output by
* e.g. echoing form elements in PHP-based template.
*
* This renderer does almost no form processing, serving as a container for
* JavascriptBuilder instance. The only processing it does is grouping errors
* and hidden elements if the relevant 'group_hiddens' and 'group_errors'
* options are set to true. It also checks whether the form contains required
* elements (and thus needs a required note).
*
* While almost everything in this class is defined as public, its properties
* and those methods that are not published (i.e. not in array returned by
* exportMethods()) will be available to renderer plugins only.
*
* The following methods are published:
* - {@link getErrors()}
* - {@link getHidden()}
* - {@link hasRequired()}
