+- [ ] experiences:
+ - [x] compare against UDF (this will not be possible, unless we use a real
+ CR-ROM) (we used git storage for an approximation)
+ - [x] make multiple repo versions with multiple parameters
- smaller block size
+ - [ ] use export in bench to compare the performance when all chunks are
+ compressed at once.
+- [ ] `init` command to initialize repo
+ - [ ] remove `chunkSize` parameter from all commands, keep it only on `init`
+ - [ ] `init` would save the important parameters of the repo, such as:
+ - the bloc size
+ - the delta algorithm
+ - the compression algorithm
+ - the sketch parameters
+ - ...and almost every value of the `NewRepo` constructor
+ - [ ] these parameters would be loaded in the `*Repo.Init()` function
