 * A concrete renderer for HTML_QuickForm, makes an array of form contents
 *
 * Based on old toArray() code.

 *   'javascript'       => 'javascript for client-side validation',
 *   'attributes'       => 'attributes for <form> tag',
 *   'requirednote      => 'note about the required elements',
 *   // if we set the option to collect hidden elements
 *   'hidden'           => 'collected html of all hidden elements',
 *   // if there were some validation errors:
 *   'errors' => array(
 *     '1st element name' => 'Error for the 1st element',
 *     ...
 *     'nth element name' => 'Error for the nth element'
 *   ),
 *   // if there are no headers in the form:
 *   'elements' => array(
 *     element_1,
 *     ...
 *     element_N

 *   'sections' => array(

 *          ...
 *          element_KM
 *       )

 * );
 *
 * where element_i is an array of the form:
 * array(
 *   'name'      => 'element name',
 *   'value'     => 'element value',
 *   'type'      => 'type of the element',
 *   'frozen'    => 'whether element is frozen',
 *   'label'     => 'label for the element',
