/**
 * Base-class for storage and retrieval of translated entities.
 *
 * Please see the 'translatable' module for managing translations of database-content.
 *
 * <b>Usage</b>
 *
 * PHP:
 * <code>
 * _t('MyNamespace.MYENTITY', 'My default natural language value');
 * _t('MyNamespace.MYENTITY', 'My default natural language value', 'My explanatory context');
 * sprintf(_t('MyNamespace.MYENTITY', 'Counting %s things'), 42);
 * </code>
 *
 * Templates:
 * <code>
 * <%t MyNamespace.MYENTITY 'My default natural language value' %>
 * <%t MyNamespace.MYENTITY 'Counting %s things' s=$ThingsCount %>
 * <%t MyNamespace.MYENTITY 'Counting {count} things' count=$ThingsCount %>
 * </code>
 *
 * Javascript (see framework/client/dist/js/i18n.js):
 * <code>
 * ss.i18n._t('MyEntity.MyNamespace','My default natural language value');
 * </code>
 *
 * File-based i18n-translations always have a "locale" (e.g. 'en_US').
 * Common language names (e.g. 'en') are mainly used in the 'translatable' module
 * database-entities.
 *
 * <b>Text Collection</b>
 *
 * Features a "textcollector-mode" that parses all files with a certain extension
 * (currently *.php and *.ss) for new translatable strings. Textcollector will write
 * updated string-tables to their respective folders inside the module, and automatically
 * namespace entities to the classes/templates they are found in (e.g. $lang['en_US']['AssetAdmin']['UPLOADFILES']).
 *
 * Caution: Does not apply any character-set conversion, it is assumed that all content
 * is stored and represented in UTF-8 (Unicode). Please make sure your files are created with the correct
 * character-set, and your HTML-templates render UTF-8.
 *
 * Caution: The language file has to be stored in the same module path as the "filename namespaces"
 * on the entities. So an entity stored in $lang['en_US']['AssetAdmin']['DETAILSTAB'] has to
 * in the language file cms/lang/en_US.php, as the referenced file (AssetAdmin.php) is stored
 * in the "cms" module.
 *
 * <b>Locales</b>
 *
 * For the i18n class, a "locale" consists of a language code plus a region code separated by an underscore,
 * for example "de_AT" for German language ("de") in the region Austria ("AT").
 * See http://www.w3.org/International/articles/language-tags/ for a detailed description.
