> ML attribute documentation is currently minimal.  This has led to confusion in some Spark PRs about how to use them.
> We should add:
> * Scala doc
> * examples in the programming guide
> The docs should make at least these items clear:
> * What the different attribute types are
> * How an attribute and attribute group differ
> * Example usage creating, modifying, and reading attributes
> * Explanation that missing attributes are OK and can be computed/added lazily
