In [90bd7900c033dccbc3cbeb5d5cb89a7903ceedfe]:

Rework the vector framework for user and item vectors

* Introduce UserVector, ItemVector, and rating-specific subclasses
* Generalize `VectorNormalizer` to support normalizing various vectors (refs #97)
* Rework recommender interface to use `UserRatingVector` rather than user ID and rating vector
* Introduce `freeze()` method to make immutable vectors from mutable ones (this is instead of implicit copy-on-write; closes #50)
* Update release notes for all of this

Would like to test this for 0.2.

To do this, we should implement it in a separate branch and performance-test it.
