Propagate exception messages from python extensions of BornAgain library
|Status:||Resolved||Start date:||07 Dec 2017|
|Target version:||Sprint 36|
If an exception is thrown in e.g. DefaultFitObserver, its message is replaced by SWIG with
terminate called after throwing an instance of 'Swig::DirectorMethodException'
what(): SWIG director method error. Error detected when calling 'IFitObserver.notify'
Original messages would be much more informative
