/**
 * 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()}
