/**
* A renderer for HTML_QuickForm2 building an array of form elements
*
* Based on Array renderer from HTML_QuickForm 3.x package
*
* The form array structure is the following:
* <pre>
* array(
* 'id' => form's "id" attribute (string),
* 'frozen' => whether the form is frozen (bool),
* 'attributes' => attributes for <form> tag (string),
* // if form contains required elements:
* 'required_note' => note about the required elements (string),
* // if 'group_hiddens' option is true:
* 'hidden' => array with html of hidden elements (array),
* // if 'group_errors' option is true:
* 'errors' => array(
* '1st element id' => 'Error for the 1st element',
* ...
* 'nth element id' => 'Error for the nth element'
* ),
* 'elements' => array(
* element_1,
* ...
* element_N
* )
* );
* </pre>
* Where element_i is an array of the form
* <pre>
* array(
* 'id' => element id (string),
* 'type' => type of the element (string),
* 'frozen' => whether element is frozen (bool),
* // if element has a label:
* 'label' => 'label for the element',
* // note that if 'static_labels' option is true and element's label is an
* // array then there will be several 'label_*' keys corresponding to
* // labels' array keys
* 'required' => whether element is required (bool),
* // if a validation error is present and 'group_errors' option is false:
* 'error' => error associated with the element (string),
* // if some style was associated with an element:
* 'style' => 'some information about element style (e.g. for Smarty)',
*
* // if element is not a Container
* 'value' => element value (mixed),
* 'html' => HTML for the element (string),
*
* // if element is a Container
* 'attributes' => container attributes (string)
* // only for groups, if separator is set:
* 'separator' => separator for group elements (mixed),
* 'elements' => array(
* element_1,
* ...
* element_N
* )
* );
* </pre>
*
* 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 reset()}
* - {@link toArray()}
* - {@link setStyleForId()}
