/*
MULTILINGUAL TEXT CODE GENERATOR 
This code generator is used to conveniently compare the english master text file with another foreign language 
such as German and verify that the appropriate language file is in perfect synch with the English.  Verifying 
that all of the strings have the correct order of printf format specifiers and the precise number.  If 
different, the errors are recorded via comments proceeding the string in question in the new file.  For 
simplicity, the German language will be used in examples throughout this documention.  The comments will be
specially marked with "CONFLICT#xxx:  error message" which can be searched for.  The comment will report 
the format specifiers used in the english version.

ASSUMPTIONS
- No functions exist in any of the master files
- Users don't use single strings using:
		STR16 str[] = L"Single String";
	Instead use:
		STR16 str[] = 
		{
			L"Single String";
		}
- Users don't use comments containing the { character later followed by the L" token.  The code generator 
  will mistaken that for a string.
- Users don't use nested braces (2D text arrays)
