Thanks for this!

1) Agreed, caching might not be great for large files. I don't think this is the only way though. I think there is another approach, that I haven't explored, which is storing a pointer to the last known Data block in each Range block. This means that you can just jump directly to the actual data without having to go through this regeneration or caching process. The space cost of this would be pretty low, one int per block, but it would mean that you wouldn't need to iterate through every change. Still figuring this out though and caching would be the best option if this doesn't work.

2) Yes I haven't totally figured this out yet. I'll give this a look, thanks!
