/**
 * Wrapper around the TYPO3 localization utility to change the default behaviour
 * for the localization.
 *
 * A new syntax is introduced to shorten the localization path.
 *
 * Moreover, if the given key does not correspond to an existing localization
 * entry it is returned unmodified.
 *
 * ---
 *
 * The shorten syntax looks like:
 *
 * `[path to localization file]:[localization key]`
 *
 * - The path to the localization file is relative to the registered extensions'
 *   private resources folder, without the file extension needed (`.xlf`).
 *
 * - The localization key is the same as in a classical localization path.
 *
 * For example, giving...
 *
 * `Events/MyEvent:some_event.label`
 *
 * ...will actually fetch:
 *
 * `LLL:EXT:my_extension/Resources/Private/Language/Events/MyEvent/MyEvent.xlf:some_event.label`
 *
 * To register a new extension key to be used in the shorten version, put the
 * following code in your `ext_localconf.php` file:
 *
 * `\CuyZ\Notiz\Service\LocalizationService::get()->addExtensionKey('my_extension');`
