vec-expr or vec *=: vec-expr

> Key: MAHOUT-1756
> URL: https://issues.apache.org/jira/browse/MAHOUT-1756
> Project: Mahout
> Issue Type: Improvement
> Reporter: Dmitriy Lyubimov
> Assignee: Suneel Marthi
> Fix For: 0.10.2, 0.11.0
>
>
> Matrices support expressions like a *=: b (do elementwise a*b on b in-place)
> but vectors don't. sometimes it is highly desirable to do that type of
> expression, and for consistency, we should enable this for vectors too.
