N. Taylor Mullen 92111ea515 Make Block and Span cache Length.
- Part of caching length required the `Span`'s `ReplaceWith` method to propagate its changes to its parent so that it can propogate the change to invalidate all parent length caches.
- Added Span and Block tests to validate the interaction of caching.
