/**
* 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.
* Overwrites 'help-messages'.
* 'help-messages' -- array of message key. As above, each item can
* be an array of msg key and then parameters.
* Overwrites 'help-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.
*
* TODO: Document 'section' / 'subsection' stuff
