// in order to control from an external application the computation of
// a DicomDir object (see DicomDir::SetStartMethod*,
// DicomDir::SetProgressMethod* and DicomDir::SetEndMethod*).
// Motivation: since DicomDir parsing can be quite long, a GUI application
//             needs to display the avancement and potentially offer a
//             cancel method to the user (when this one feels things are
//             longer than expected).
// Example of usage: refer to demo/DicomDirProgressMethod.py
// Note: Uses gdcmPythonVoidFunc and gdcmPythonVoidFuncArgDelete defined
//       in the Swig verbatim section of this gdcm.i i.e. in the above section
//       enclosed within the %{ ... %} scope operator ).
