** Included dcmodify in MSVC build system, updated headers
**
** Revision 1.23  2003/06/12 13:29:28  joergr
** Fixed inconsistent API documentation reported by Doxygen.
**
** Revision 1.22  2002/12/06 12:49:17  joergr
** Enhanced "print()" function by re-working the implementation and replacing
** the boolean "showFullData" parameter by a more general integer flag.
** Added doc++ documentation.
** Made source code formatting more consistent with other modules/files.
**
** Revision 1.21  2002/08/27 16:55:40  meichel
** Initial release of new DICOM I/O stream classes that add support for stream
**   compression (deflated little endian explicit VR transfer syntax)
**
** Revision 1.20  2002/04/25 10:03:45  joergr
** Added getOFString() implementation.
** Added/modified getOFStringArray() implementation.
** Added support for XML output of DICOM objects.
**
** Revision 1.19  2001/10/02 11:47:34  joergr
** Added getUint8/16 routines to class DcmOtherByteOtherWord.
**
** Revision 1.18  2001/09/25 17:19:32  meichel
** Adapted dcmdata to class OFCondition
**
** Revision 1.17  2001/06/01 15:48:51  meichel
** Updated copyright header
**
** Revision 1.16  2000/11/07 16:56:10  meichel
** Initial release of dcmsign module for DICOM Digital Signatures
**
** Revision 1.15  2000/04/14 15:31:34  meichel
** Removed default value from output stream passed to print() method.
**   Required for use in multi-thread environments.
**
** Revision 1.14  2000/03/08 16:26:24  meichel
** Updated copyright header.
**
** Revision 1.13  2000/03/03 14:05:27  meichel
** Implemented library support for redirecting error messages into memory
**   instead of printing them to stdout/stderr for GUI applications.
**
** Revision 1.12  2000/02/10 10:50:55  joergr
** Added new feature to dcmdump (enhanced print method of dcmdata): write
** pixel data/item value fields to raw files.
**
** Revision 1.11  1999/03/31 09:25:03  meichel
** Updated copyright header in module dcmdata
**
** Revision 1.10  1998/11/12 16:47:51  meichel
** Implemented operator= for all classes derived from DcmObject.
**
** Revision 1.9  1997/07/21 08:25:15  andreas
** - Replace all boolean types (BOOLEAN, CTNBOOLEAN, DICOM_BOOL, BOOL)
**   with one unique boolean type OFBool.
**
** Revision 1.8  1997/05/27 13:48:30  andreas
** - Add method canWriteXfer to class DcmObject and all derived classes.
**   This method checks whether it is possible to convert the original
**   transfer syntax to an new transfer syntax. The check is used in the
**   dcmconv utility to prohibit the change of a compressed transfer
**   syntax to a uncompressed.
**
** Revision 1.7  1997/05/16 08:31:20  andreas
** - Revised handling of GroupLength elements and support of
**   DataSetTrailingPadding elements. The enumeratio E_GrpLenEncoding
**   got additional enumeration values (for a description see dctypes.h).
**   addGroupLength and removeGroupLength methods are replaced by
**   computeGroupLengthAndPadding. To support Padding, the parameters of
**   element and sequence write functions changed.
**
** Revision 1.6  1997/04/18 08:13:31  andreas
** - The put/get-methods for all VRs did not conform to the C++-Standard
**   draft. Some Compilers (e.g. SUN-C++ Compiler, Metroworks
**   CodeWarrier, etc.) create many warnings concerning the hiding of
**   overloaded get methods in all derived classes of DcmElement.
**   So the interface of all value representation classes in the
**   library are changed rapidly, e.g.
**   OFCondition get(Uint16 & value, const unsigned long pos);
**   becomes
**   OFCondition getUint16(Uint16 & value, const unsigned long pos);
**   All (retired) "returntype get(...)" methods are deleted.
**   For more information see dcmdata/include/dcelem.h
**
** Revision 1.5  1996/08/05 08:45:33  andreas
** new print routine with additional parameters:
**         - print into files
**         - fix output length for elements
** corrected error in search routine with parameter ESM_fromStackTop
**
** Revision 1.4  1996/01/29 13:38:17  andreas
** - new put method for every VR to put value as a string
** - better and unique print methods
**
** Revision 1.3  1996/01/05 13:23:07  andreas
** - changed to support new streaming facilities
** - more cleanups
** - merged read / write methods for block and file transfer
