                 C++ exception for throwing python exceptions

 Purpose: A C++ exception class for throwing python exceptions
          through C++ code.
 Created: Apr, 2004, sss, from the version in D0's python_util.

 Note: Don't be tempted to declare the virtual functions defined here
       as inline.
       If you do, you may not be able to properly throw these
       exceptions across shared libraries.
