A crate for handling the references stored in various formats in a git repository.
References are also called refs which are used interchangeably.
Refs are the way to keep track of objects and come in two flavors.

- peeled refs point to the an object by its [ObjectId][git_hash::ObjectId]
They can be identified by a relative path and stored in various flavors.
- files
- [loose][file::Store]
- one reference maps to a file on disk
- packed
- references are stored in a single human-readable file, along with their targets if they are symbolic.
