Early versions of this class kept the stack in memory as a singleton, but I
found it made no appreciable difference in real apps, so I removed it for
simplicity. If you WANT TO pass the stack around, go ahead and do so,
there's nothing stopping you.
But please note: Apple's approach is wrong and very dangerous, since their
code is not thread-safe, in a "bad" way. It's best for each class to own
its own local stack of CD classes, and be guaranteed that no other thread
is messing with them.
This is how Apple designed CoreData to work!

Hello Adam,
I stumbled upon this helper class you made and while I like the idea, I
noticed you don't follow Apple convention of passing the context from the
Application Delegate to the subsequent view controllers.Instead, you seem to load everything up every time you want to operate
with core data. I don't know if this is is more correct but I wanted your
opinion on why you made it this way.What I mean is, loading a managed object model from disk in every view
controller, just seems like you will make the app spend to much time
loading the model when you can easily pass a pointer to the
ManagedObjectContext instance to your controllers.The only reason I can see for doing this is having more than one model,
but maybe I am not seeing something.Well, thank you in advance for your reply.
