+Garbage collection / cache management support

+Middleware that knows how to pull annoMatrix from the undoable state,
+and pass it along to the AnnoMatrix class for possible cache GC.

+Private interface.
+
+Future work item: this middleware knows internal details of both the
+Undoable metareducer and the AnnoMatrix private API.  It would be helpful
+to make the Undoable interface better factored.
