For Janek's sake, you just define a simple traits type for any vector
type, and the generic vector operations in (Boost) LA kick-in

I've also implemented generic quaternion operations in (Boost) LA that
kick-in for user-defined types, but I haven't yet published that code
because I haven't got a chance to update the documentation. Hopefully
