fe65b1c129 Add Vector::axcpy method 
The added method `Vector::axcpy` generalises `Vector::gemv` to
noncommutative cases since it allows us to write for `gemv`
`self.axcpy(alpha, &col2, val, beta)`, instead the usual
`self.axpy(alpha * val, &col2, beta)`. Hence, `axcpy` preserves the
order of scalar multiplication which is important for applications where
commutativity is not guaranteed (e.g., matrices of quaternions, etc.).

This commmit also removes helpers `array_axpy` and `array_ax`, and
replaces them with `array_axcpy` and `array_axc` respectively, which
like above preserve the order of scalar multiplication.

Finally, `Vector::axpy` is preserved, however, now expressed in terms of
`Vector::axcpy` like so:

```
self.axcpy(alpha * val, &col2, beta)
```

e1c8e1bccf Fix Vector::axpy for noncommutative cases 
One example would be performing simple matrix multiplication
over a division algebra such as quaternions.

74aefd9c23 Improve precision of UnitQuaternion::angle (#569) 
The previous implementation had stability problems for small angles due
to the behaviour of the arccosine it used. In particular, it needs a
hack to handle "cosines" greater than 1 and the smallest obtainable
nonzero angle for e.g. f32 is acos(1-2^-22) = 0.00069...
These problems can be fixed by using an arctangent-based formula.
