-/**
- * Object handling generic submission, CSRF protection, layout and
- * other logic for UI forms. in a reusable manner.
- *
- * In order to generate the form, the HTMLForm object takes an array
- * structure detailing the form fields available. Each element of the
- * array is a basic property-list, including the type of field, the
- * label it is to be given in the form, callbacks for validation and
- * 'filtering', and other pertinent information.
- *
- * Field types are implemented as subclasses of the generic HTMLFormField
- * object, and typically implement at least getInputHTML, which generates
- * the HTML for the input field to be placed in the table.
- *
- * The constructor input is an associative array of $fieldname => $info,
- * where $info is an Associative Array with any of the following:
- *
- * 'class' -- the subclass of HTMLFormField that will be used
- * to create the object. *NOT* the CSS class!
- * 'type' -- roughly translates into the <select> type attribute.
- * if 'class' is not specified, this is used as a map
- * through HTMLForm::$typeMappings to get the class name.
- * 'default' -- default value when the form is displayed
- * 'id' -- HTML id attribute
- * 'cssclass' -- CSS class
- * 'options' -- varies according to the specific object.
- * 'label-message' -- message key for a message to use as the label.
- * can be an array of msg key and then parameters to
- * the message.
- * 'label' -- alternatively, a raw text message. Overridden by
- * label-message
- * 'help-message' -- message key for a message to use as a help text.
- * can be an array of msg key and then parameters to
- * the message.
- * 'required' -- passed through to the object, indicating that it
- * is a required field.
- * 'size' -- the length of text fields
- * 'filter-callback -- a function name to give you the chance to
- * massage the inputted value before it's processed.
- * @see HTMLForm::filter()
- * 'validation-callback' -- a function name to give you the chance
- * to impose extra validation on the field input.
- * @see HTMLForm::validate()
- * 'name' -- By default, the 'name' attribute of the input field
- * is "wp{$fieldname}". If you want a different name
- * (eg one without the "wp" prefix), specify it here and
- * it will be used without modification.
- *
