  * python/distutilsSwigCPlusPlus.py now properly collects the
        shadow classes generated by "swig -c++" (gdcm.py in our case)
        when using "python setup.py install".
      * python/gdcmPython/__init__.py imports gdcm.py and only manually
        reexports the working classes.
      * src/gdcmHeader.cxx all the try/catch/throw calls were replaced
        by the classical C errno scheme. This is to prevent an obscure
        behavior of the python wrappers when importing wxPython.wx prior
        to gdcmPython (which ended up in an abort call). An illustration
        of this oddity can be found in the Test/ExceptionAndPython
        subdir (see the README file). This problem probably due to
        an combination of g++ and dynamic loading.
