/**
*CVS Log info
*$Log$
*Revision 1.3  2004/12/01 04:31:42  ddiego
*merged over devmain-0-6-6 code. Marcello did a kick ass job
*of fixing a nasty bug (1074768VCF application slows down modal dialogs.)
*that he found. Many, many thanks for this Marcello.
*
*Revision 1.2.2.1  2004/11/10 19:09:47  marcelloptr
*fixed documentation for doxygen
*
*Revision 1.2  2004/08/07 02:49:16  ddiego
*merged in the devmain-0-6-5 branch to stable
*
*Revision 1.1.2.6  2004/07/29 02:39:14  ddiego
*fixed a bug with File::getINputStream and File::getOutputStream.
*
*Revision 1.1.2.5  2004/07/24 01:40:42  ddiego
*committed changes requested by Marcello. Got rid of the remaining
*date time members on the File class - now the dat time function call the
*FilePeer directly each time. Also added 2 functions to DateTime to convert
*directly to UTC or Local time.
*
*Revision 1.1.2.4  2004/07/19 04:08:53  ddiego
*more files and directories integration. Added Marcello's Directories example as well
*
*Revision 1.1.2.3  2004/07/18 14:45:19  ddiego
*integrated Marcello's new File/Directory API changes into both
*the FoundationKit and the ApplicationKit. Many, many thanks go out
*to Marcello for a great job with this. This adds much better file searching
*capabilities, with many options for how to use it and extend it in the
*future.
*
*Revision 1.1.2.2  2004/04/29 04:07:14  marcelloptr
*reformatting of source files: macros and csvlog and copyright sections
*
*Revision 1.1.2.1  2004/04/28 03:29:41  ddiego
*migration towards new directory structure
*
*Revision 1.10.4.2  2004/04/26 21:58:43  marcelloptr
*changes for dir reorganization: _VCF_MACRO_H__
*
*Revision 1.10.4.1  2004/04/21 02:17:23  ddiego
*checking in change to FoundationKit, GraphicsKit and Application
*Kit to support unicode in Win32
*
*Revision 1.10  2003/12/18 05:15:58  ddiego
*merge from devmain-0-6-2 branch into the stable branch
*
*Revision 1.9.4.1  2003/10/23 04:24:51  ddiego
*more musical chairs with headers again, in yet another attempt to make
*them more efficent to speed up compiles.
*Removed all teh template RTTI classes and put them all in one header
*called VCFRTTIImpl.h. This should help compile speeds a bit.
*The next step is to look at some of the event classes and remove ones
*that aren't really neccessary - I'd estimate that 50% of the current
*event classes are unneccessary and can be removed.
*
*Revision 1.9  2003/05/17 20:37:13  ddiego
*this is the checkin for the 0.6.1 release - represents the merge over from
*the devmain-0-6-0 branch plus a few minor bug fixes
*
*Revision 1.8.16.1  2003/03/12 03:11:19  ddiego
*switched all member variable that used the "m_"<name> prefix to
* <name>"_" suffix nameing standard.
*Also changed all vcf builder files to accomadate this.
*Changes were made to the Stream classes to NOT multiple inheritance and to
*be a little more correct. Changes include breaking the FileStream into two
*distinct classes, one for input and one for output.
*
*Revision 1.8  2002/05/09 03:10:43  ddiego
*merged over code from development branch devmain-0-5-1a into the main CVS trunk
*
*Revision 1.7.4.1  2002/03/20 21:56:56  zzack
*Changed Include Style of FoundationKit

*added a cvs "log" comment to the top of all files in vcf/src and vcf/include
*to facilitate change tracking
