 In OpenScientist-13 AIDA implementation, someone can't do directly a delete over
an AIDA::ITree. The trees are managed by the IAnalysisFactory and are deleted by it
when doing a delete ovr the af. Then with this version doing :
   delete tree;
   delete af;
will crash.

Discussions within the AIDA group showed that we had a semantic misunderstanding about the deletion of trees. In principle now it is fixed and it had been agreed that the implementations should permit the "delete tree" by a user program.

For the OpenScientist implementation it is going to be fixed with the OpenScientist-14 (still over AIDA-3.2.1) which is going to be released soon. Anyway, even with this version, someone will have to delete the analysis factorie(s) after dealing with the trees, since the analysis factories are still managers of trees in OpenScientist/Lab.

Then for the moment (and if working with OpenScientist-13) comment out the "delete tree" when working with the various G4 examples.

I shall notify also here when the OpenScientist-14 will be ready (probably begin of next week for the source tar file).
