Yes, I have designed new C-style MIDAS ODB APIs twice now (VirtualOdb in ROOTANA and MVOdb in ROOTANA and MIDAS),
and I was never happy with the results. There is too many corner cases and odd behaviour. Let's see how
this C++ interface shakes out.

For use in analyzers, Stefan's C++ interface still need to be virtualized - right now it has only one implementation
with the MIDAS ODB backend. In analyzers, we need XML, JSON (and a NULL ODB) backends. The API looks
to be clean enough to add this, but I have not looked at the implementation yet. So "watch this space" as they say.

K.O.
