* The macro definitions for debug
*
* These macros are defined in static. If you want to use debug macro, you can
* use as following code:
*
* In your C/C++ file, enable/disable DEBUG_ENABLE macro, and then include this
* header file.
*
* #define DBG_SECTION_NAME "[ MOD]"
* #define DBG_ENABLE // enable debug macro
* #define DBG_LEVEL DBG_INFO
* #include <rtdbg.h> // must after of DEBUG_ENABLE or some other options
*
* Then in your C/C++ file, you can use dbg_log macro to print out logs:
* dbg_log(DBG_INFO, "this is a log!\n");
*
* Or if you want to using the simple API, you can
* LOG_D("this is a debug log!");
* LOG_E("this is a error log!");
*
* If you want to use different color for different kinds log, you can
* #define DBG_COLOR
