   * src/jpeg/libijg12/jdhuff12.c:
      - printf polluting ctest removed.
      - TAB removal for comminting
   * Test:
     - TestAllReadCompareDicom.cxx: added a test that compares all the
       images in gdcmDataImages.h with corresponding images in
       gdcmData/BaselineDicom/. When baseline images are not present
       this test creates them.
       Note: we need to validate each reference image, but before that
             I'd like to rename them with a more explicit name...
     - CMakeLists.txt: changed accordingly.
   * Example/*.cxx: examples now only include gdcm.h (as opposed to
     including each header needed).
