analysis/Ana needs to be updated to account for several API changes (I think).

The truth info has changed like this according to Mike McCumber:

This is a conflict with the new truth info design which forced the deprecation of that piece of the interface (poor encapsulation in the original object). To loop of the primary tracks you will need to use these lines:

PHG4TruthInfoContainer::ConstRange range = truthinfo->GetPrimaryParticleRange();
for (PHG4TruthInfoContainer::ConstIterator iter = range.first;
iter != range.second; 
++iter) {
  PHG4Particle* primary = iter->second;
}

I think there must have been a change to the Fun4All input manager as well.

The example should probably have a small DST that can be used for testing and will always be available when the code is built.
