  * CLEANUP_ROUND (13) for gdcmPixelConvert
    Substituted File::ParsePixelData() with PixelConvert::Print() new
    method:
    - src/gdcmParsePixels.cxx removed (only contained File::ParsePixelData())
    - src/gdcmRLEFrame.cxx, gdcmJPEGFragment.cxx added. Added a ::Print()
      method to those classes.
    - src/gdcmFile.[cxx|h]:
      -- Added a ::Print() method.
      -- PixelConverter is now a reference instead of a member.
      -- gdcmPython/gdcm.i: added "using namespace gdcm" in order for
         gdcm_wrap.cxx to "understand" File::GetPixelConverter()
