Detailed Description

this class can output to the cmd window and log files simultaneously. In wb-log.cpp, there are a Log variable "lout", which can be directly used just like "cout". For example:

Author

WangBin

Date

2013-8-29

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;
6. Include a progress bar function which can output a progress bar on the console window
