/**
 * Language Column
 *
 * Object representation of a site language selected in the "page" module
 * to show translations of content elements.
 *
 * Contains getter methods to return various values associated with a single
 * language, e.g. localized page title, associated SiteLanguage instance,
 * edit URLs and link titles and so on.
 *
 * Stores a duplicated Grid object associated with the SiteLanguage.
 *
 * Accessed from Fluid templates - generated from within BackendLayout when
 * "page" module is in "languages" mode.
 *
 * @internal this is experimental and subject to change in TYPO3 v10 / v11
