Store the highest enclosing directory as the global dictionary key.
Improve suspend/resume behavior and extend it to BIFF documents.
Get rid of the notion of suspending, since stopping the AUGraph works the same and is more efficient.
Remove a Snow-only search field attribute.
Load the BIFF in the main thread and use the NSError if there's no audio.
Version bump.
Forgot to move the suspend/resume declarations to ACMDocumentCommon.h.
