Changes based on a code review for DICOM PM (D141) Added Header file and refactored the interface of the DICOMSegPropertyHandler. Handler distinguishes the handling of special DICOM Seg properties and the handling of DICOM Tags from the sourde image now. Second one will be needed in other derived DICOM Images like PM or other. TODO: Move this part to a more genaeralized class
Adding the Properies to the BaseData as well as to the labels is no longer done in the GUI classes.
