-----------------------------------------------------------------------------
-Switch from errno C-style to exceptions:
- Goal: remove all the C-oriented errno (#include <errno.h>) and switch
- to C++ exceptions.
- Note: - only src/gdcmDocument.cxx includes errno.h
- - when exceptions were first introduced within gdcm, it caused
- gdcmPython to be uncompatible within the corresponding version
- of wxPython (refer to the first lines of
- Test/ExceptionAndPython/README). Hence we reverted to the old
- errno mecanisme. Since wxPython seems not to be problem anymore
- (check it with Test/ExceptionAndPython) we can now move back to C++
- exceptions.
------------------------------------------------------------------------------
-CLEANUP:
- - Remove ignore_shadow from gdcmDocument().
------------------------------------------------------------------------------
* vtk/vtkGdcmHeader.cxx: if speed becomes a concern some changes can
be made at the cost of memory consumption (refer to header of
vtk/vtkGdcmHeader.cxx)
