Description

Hey, first off, great library. I'm one of the authors of Spire (w/ Erik Osheim @non). Looking over some of the type classes, we seem to be duplicating some work (wrt algebra type classes). Breeze has a much larger scope than Spire, so I was wondering if there was anything you'd like to see in Spire that'd let you replace breeze.math with Spire's type classes (checkout spire.algebra). A VectorSpace typeclass seems a minimum, but is there anything else?

If you all are amenable, I could try submitting a PR for a version of breeze that uses Spire's type classes where appropriate. If you aren't interested, than no worries, just le me know and I won't do the work :)

Research direction
Explore the existing breeze.math package and compare with Spire's algebra type classes (e.g., spire.algebra.VectorSpace). Review the comments on this issue for additional requirements from maintainers. Assess the effort to refactor breeze to depend on Spire, including potential changes to build dependencies and type class hierarchies.
