-/**
- * 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.
