Ref Values now have a TargetRef() method that returns the ref.Ref of
the target the Value is referencing.
Note: This is a breaking change. In old code the Ref() of the Value was
the Ref of the underlying target.
Fixes#464
This makes the new typed serialization the default (the old
serialization is not used but the code has not been cleaned up yet).
Some things are no working in the new world:
Chunking - The compound list is not working correctly any more. The
Chunks method is having issues because it assumed things based on the
old implicit chunking.
Commit - uses a `Set(Commit)` which means that the parent commit is
embedded. We need to change that to be `Set(Ref(Commit))` so that the
parent commit is referenced instead.
Instead of returning errors, these now use d.Exp to raise catchable
errors.
Also, added commit hash at which code was pulled from encoding/json
Marshal io.Reader into a Blob, unmarshal Blob into io.Writer
Unmarshal and Marshal are tools for moving data from Noms into native Go and
back. The rules are described in the documentation of the two functions, but
the behavior is broadly similar to encoding/json.
Towards issue #160
The plan is to modify the encoding/json code heavily for use in
marshaling between native Go and Noms values. This pulls in the files
unmodified so we have a record of our changes.
