	* There are 3 functions to write to a log file, which may be used in accordance with the following rules:
	*
	*	1. The user always knows whether he is writing to an ANSI file or a Unicode file, and he
	*		has to make sure this holds good in the rules 2, 3 and 4 below. This will be changed later to
	*		make it more flowxible to the user.
	*	2. Write() takes TCHAR arguments and the function will write and ANSI or Unicode string
	*		to the log file depending on what TCHAR maps to, in the compilation.
	*	3. WriteW() takes WCHAR arguments only, and expects that the file being written to is a Unicode file.
	*	4. WriteA() takes char arguments only, and expects that the file being written to is an ANSI file.
