 [ ] Add notes on benchmarks and that we don't do batching
 [ ] Fix endianess when writing to network and the WAL
 [ ] Add a change counter to FileTree. The counter is initialized to 0 and updated any time the tree is changed. When a new file is created, the current change counter is assigned to it. This makes it possible to verify that the file didn't change in between read and write operations without that clumsy previous hash list and previous chunk size.
