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.
