  * src/gdcmHeader.cxx :
        - RecupLgr renamed to FindLength and cut off with new IsAnInteger
          method.
        - SetLgrElem renamed to SetLength
        - GetLgrElem renamed to GetLength
        - ~gdcmHeader() made virtual to pesky warning messages at compile.
      * src/gdcmElValSet.cxx fixed both GetElValue methods
      * Dicts/dicomV3.dic falacious entry [7fe0 0010 OT PXL Pixel Data]
