I've updated the proposal.  I've simplified the API quite a bit.  I  
realized that we didn't need the methods for iterating over objects  
and object revisions, since we can use the existing storage iteration  
API and because, for FileStorage, simply iterating over the storage  
will more efficient.  (It's possible that, at some time in the future,  
there could be an advantage for an iterator for oid/tid pairs that  
returns values in an order defined for the storage.)
