***  MODULE NAME	BSIPLogger.h
***
***  PROJECT		BattleSIP
***
***  DESCRIPTION	BSIPLogger includes a few macros that can be used to record 
***                 information of interest to the user. Log file is stored to 
***                 c:\Logs\BattleShip\debug.log. 
***
***					EXAMPLES:
***					#ifdef __DEBUGLOGGER__
***						//Writes 'Some text' to the log
***						WRITE_LOG(_L("Some text"));
***					#endif __DEBUGLOGGER__
***					
***					#ifdef __DEBUGLOGGER__
***						//Writes formated text to the log
***						TInt num1=100;
***						WRITE_LOG_FORMAT(_L("Writing a number to the log: %d"), num1);
***					#endif __DEBUGLOGGER__
***					
***					#ifdef __DEBUGLOGGER__
***						// Line begins with time only
***						SET_LOG_DATE_TIME( EFalse, ETrue);		
***					#endif __DEBUGLOGGER__
***					
***					#ifdef __DEBUGLOGGER__
***						WRITE_LOG(_L8("HexDump Test"));
***						const TText* hdr=_S("123456");
***						const TText* mgn=_S("      ");
***						const TUint8* ptr=_S8("abcdefghijklmnopqrstuxyz");
***						TInt len=26;
***						LOG_HEX_DUMP(hdr,mgn,ptr,len);
***					#endif __DEBUGLOGGER__
