	Programmer: Ludvik Jerabek

    Defined Classed: CIniFileW CIniFileA

	Purpose: C++ Inifile Reader\Writer. Uses std::set and stdext::hash_set to implement an efficient ini object.

	Summary: This is a total re-write of the original CIniFile class written in 2006. Originally the data structures
             underlying the CIniFile object were std::list which was extreamly inefficient when dealing with huge ini files.


		   Note: The class currently supports std::wstring and std::string. The typedef CIniFile is based on the whether of no
                 _UNICODE is defined. If _UNICODE is define in your project CIniFile is a CIniFileW if _UNICODE is not defined
                 then CIniFile is a CIniFileA object.

		   Defines:

		           _TRACE_CINIFILE - If defined enables call tracing to standard output
		                  _UNICODE - If defined the CIniFile will be defined as CIniFileW instead of CIniFileA
	          _FORCE_UNIX_LINEFEED - If defined when _WIN32 is defined (WINDOWS) the default linefeed CRLF is overridden to CR
		   _FORCE_WINDOWS_LINEFEED - If defined when _WIN32 is not defined (*NIX) the default linefeed CR is overridden to CRLF

		   Updates:

            12\01\2005 - Initial MFC Release.
            01\12\2006 - Ported to Ansi C++ Non-MFC.
            06\16\2009 - Added support for different linefeed types, resolved issues around reading different types of linefeeds.
            06\17\2009 - Added support for wide characters.
            06\21\2009 - Re-written to use std::map.
            07\02\2009 - Removed MFC version. Since Ansi version works in MFC ( Examples provided for download ).
            07\03\2009 - Added support for VS6.
            07\03\2009 - Fixed issue with SecIndexA \ SecIndexW. Were not named specific to the encoding may have caused issues.
            07\03\2009 - Fixed GetKeys and GetSections functions to return const ref v.s. copy of data.
            07\14\2009 - Fixed Load() whitespace preservation on key value.
            09\21\2009 - Fixed removing all the sections and keys, replaced empty() with clear()
            09\22\2009 - Added overloaded Load() and Save() to read\write streams
            09\23\2009 - Added operators for << and >> to be used with streams
            09\24\2009 - Added merge option to Load()
            09\25\2009 - Added CIniMerge for use with << and >>
            09\27\2009 - Moved CIniMerge into CIniFile, fixed issue with VC6 CIniFile::CR
            12\29\2010 - Reduced key storage redundancy by using std::set instead of std::map
            12\29\2010 - Reduced number of pass by value methods to reduce deep copy (std::string to const std::string&)
            05\07\2011 - Fixed MSC_VER to _MSC_VER
            05\07\2011 - Fixed OTHER file parse detection issue
