[Ves] Using KiwiViewer to load a DICOM file

[Pat Marion]

Thanks, I received the data and I will take a look soon.  It's possible
that VTK's DICOM reader is not a full featured DICOM reader, and it will be
unable to read your data in full.  I'll give it a try.  Does this dataset
contain a single image slice, or multiple slices?
