lout<<"Hello Wrold!"<<endl;

"lout" has the following advantages:

1. It can output to the cmd and the log file. Besides they can be controled.
2. It can output the begin and end date of the program.
3. If the output varialbes are bools, then it will output true/false
4. If the output variables are char*, then it will detect if the pointer is NULL.
5. There are some macros, such as lout_variable, lout_error, lout_waring and so on;
