Translations
To translate some text displayed on screen you have to either create a new instance of 'limesurvey_lang' (limesurvey\classes\core\language.php) or in some cirumstances there is already an instance created called '$clang'.

To translate you call the function gT  ($clang->gT(string)). More information on how to use localization can be found here.

In general $clang is set in (limesurvey\common.php) and uses a number of variables to determine language.

$baselang
