The latest commit updates the various places where looking up a document
that doesn't exist returns null. Now an IOException is thrown with a helpful
message and guid of the missing object. I added tests to cover these cases. I
also added changes that will throw an exception when alerts to be add/removed
don't exist. Previously that wasn't covered and the operation would succeed
even though the missing alert wasn't added/removed.
For the parallel stream issue, I made it consistent with the rest of the
class. It now uses the same approach as the getLatest method and uses the
DocumentContainer class. As part of this I moved common code to a separate
method.
Let me know what you think about these changes.
