Quirks with doing simple task of creating object and then using on main thread as soon as possible about cadmium

I think I might be too heavy-handed with the guard against transferring w/o an existing context. If the NSManagedObject has a permanent objectID I should let it pass as well. I think this would make the async version work, but will test later.

In fact, I should probably be checking against temporary IDs, but I think the check on originalContext.hasChanges is doing that implicitly (since any context w/ an object that isn't saved will have changes..)

Ok, 0.11.1 is up with the change to context-checking on useInCurrentContext. Now any object with a persistent ID should be useable; still relying on the hasChanges flag to catch transient objects though.

Also added some more content to the readme about this, as well as notes on the update handler.

(btw, added code to the basic example's handleAdd function to show the object being dispatched and having an updateHandler assigned to it)

Great, looks good!
