 * \brief    gdcmDict acts a memory representation of a dicom dictionary i.e.
 *           it is a container for a collection of dictionary entries. The
 *           dictionary is loaded from in an ascii file.
 *           There should be a single public dictionary (THE dictionary of
 *           the actual DICOM v3) but as many shadow dictionaries as imagers 
 *           combined with all software versions...
