Shelves: Storing values referenced by a unique typed index.

This is a small utility library for storing values of and reference them using a unique typed index, Ref<T>, which is a simple typed wrapper around usize.

Any data structure can be used behind the shelf as long as it provides a way to store and fetch values by usize through the implementation of the Storage trait. This library provides a Storage implementation for Vec, BTreeMap and HashMap. In addition, a Storage implementation is provided for the slab::Slab type by enabling the slab-storage feature.
