+/**
+ * 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
+ * '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()
+ *
