/**
 * Class allowing to quick edit a title inline
 *
 * This class is used for displaying an element that can be in-place edited by the user. To display call:
 * echo $OUTPUT->render($element);
 * or
 * echo $OUTPUT->render_from_template('core/inplace_editable', $element->export_for_template($OUTPUT));
 *
 * Template core/inplace_editable will automatically load javascript module with the same name
 * core/inplace_editable. Javascript module registers a click-listener on edit link and
 * then replaces the displayed value with an input field. On "Enter" it sends a request
 * to web service core_update_inplace_editable, which invokes the callback from the component.
 * Any exception thrown by the web service (or callback) is displayed as an error popup.
 *
 * Callback {$component}_inplace_editable($itemtype, $itemid, $newvalue) must be present in the lib.php file of
 * the component or plugin. It must return instance of this class.
