//////////////////////////////////////////////////////////////////////////
// @author: Josephus
// @date: 2016-5-3
// @version: 1.0.0
// @edit_history: 
//	@date:2016-6-26 set option for no buffer or not.
//	@date:2016-7-2	delete erroCode stored; 
//					add Trace Logger format; add GetLastError() formatting message;
//					add LOG_FUNCION() to log function enter and leave event;
//	@date:2016-7-4	improve the logger time accurating to millisecond;
//  @date:2016-7-26 change the time-formate depend on file_mode.
//	@date:2016-7-29 support for unicode characterset.
//	@date:2016-7-29	write the log buffer into the file for specified time interval.
//	@date:2016-9-2	add 'TRACE_FUNCTION' to log function with returned value(type: int, dword).
//  @date:2016-12-2 add header file: <tchar.h>
//  @date:2017-1-24 add WRITE_ERRCODE_LOG
//  @date:2017-2-9  add FileModeEnum::CustomDir_DaySplit_Mode
//  @date:2017-5-2  add WRITE_TRACE_LOG
//	@date:2017-5-8  add LOG_ASSERT and change WRITE_TRACE_PARAM implemention.
//  @date:2017-5-18 add LAZY_MODEL definition for avoiding creating LogFiles folder.
// ----------------------------------------------------------------------------------------------
// @version: 2.0.0 #date: 2017-6-29
//	@date:2017-7-12 support creating seperated logger instance representing its own record folder
//	@date:2017-7-14 fix some bugs
//  @date:2017-10-11 fix the bugs: the order of declaration for static-type m_strLogDirOrFilePath
//                   would make the set-operation for m_strLogDirOrFilePath in  declaration routine  
//                   for CAutoWriteHelper no sense.
