fix bug in handling when arg -h/--help is used
Problem: Some unexpected exception are thrown, when arg war -h Reason: ArgParser throws SystemExit exception when -h is used Solution: 1.) Move ArgParser to the first position, to prevent create the objects 2.) make sure, the finally block of the main program will not be called 3.) catch SystemExit exception
