- Commit now returns just a single hash rather than a vec. Since the
change we create from committing has all of the heads as deps there
can only be one hash/head after committing.
- Apply changes now takes a Vec rather than a slice. This avoids having
to clone them inside.
- transact_with now passes the result of the closure to the commit
options function
- Remove patch struct
- Change receive_sync_message to return a () instead of the
`Option<Patch>`
- Change `Transaction*` structs to just `*` and use the transaction
module
- Make CommitOptions fields public
* Add quickstart example
Also change ordering of transact_with arguments.
This makes it more natural read: transact_with these commit options,
doing this.
