/**
 *
 * To set the platform logger use the logger service to specify a PSR3 compliant logger
 *
 * To use monolog logger, taoMonolog wrapper can be set as following
 *
 * `return new oat\oatbox\log\LoggerService(array(
 *     'logger' => array(
 *         'class' => \oat\oatbox\log\logger\TaoMonolog::class,
