Currently the DICOMPropertyPath class is located in DICOMReader module. But in Order to introduce more and more DICOM encoding for properties (e.g. see ImageSourcePropertyRule and the Task of helper methods to correctly set properties of base data; like Image Instance UIDs in mitk::Images) it could be handy to have this class directly in the core because it makes specifying dicom pathes easier then using PropertyPath class.

If we do that we either have to seperate DICOMPRopertyPath from DICOMTag in order to avoid building a dependency against GDCM in the core; or we accept this dependencies (because we already have it implecitly via ITK, which builds with GDCM)
