-We consider now that :
-- any dicom related file is a gdcm::Document.
-- a gdcm::Document can be :
-      - a gdcm::File,     if it contains pixel data,
-      - a gdcm::DicomDir, if it contains only informations 
-                          on the files in a given directory
-
-- in a gdcm::Document, there are gdcm::DocEntry, that can be :
-     - gdcm::ContentEntry (any entry that has an actual value,
-                           *not* an embedded set of other gdcm::DocEntry)
-                           a gdcm::ContentEntry can be :
-          - gdcm::ValEntry (whose value is std::string representable 
-                            e.g. character values, or integers),
-          - gdcm::BinEntry (whose value is not std::string representable 
-                            e.g. color palettes, overlays, icons , ...)
-     - gdcm::Sequence (no proper 'value', but a set of gdcm::SQItems, 
-                       composed of a set of gdc::DocEntry, recursively)
- 
-- in a gdcm::DicomDir, we only deal, hierarchically, with :
