-- This example shows you how to work with various log levels
--
-- The script is triggered by a dummy switch called 'test'
--
-- when no log level is specified, the level is taken from the default application settings (dzVents)
--
-- when you specify LOG_STATUS as minimum log level, no logs will be displayed when using LOG_INFO or LOG_DEBUG
--
-- Order is: LOG_DEBUG, LOG_INFO, LOG_STATUS, LOG_ERROR
--
-- LOG_DEBUG will also cause Execution Info to be displayed (start/finished)
