Now there is only one one (#513) 
* Now there is only one one

* Rotation no longer has a parameter

* Moved some type parameters to associated types

* Relaxed some bounds and simplified a bound

* Removed unnecessary bound in

* Deduplicated multiplication code

Merge #491 
491: Fix Matrix2::look_at, add look_at_stable r=kvark a=blargg

## Changes

1. Fixes `Matrix2::look_at`
2. Adds tests for `look_at`
3. Adds a new function, `look_at_stable`

## Notes
I added a new function for 2d look at rotation. `look_at` is a bit weird in practice for 2d. For example, if you are making a basis matrix to orient a 2d character to look at a point, `look_at` will flip the character as they rotate past `up` or `-up` vectors. This is the best match for what look_at is supposed to do, I think.

`look_at_stable` will not flip based on orientation, you just pass in which way to flip. This is a bit easier to use to rotate 2d characters.

`look_at_stable` could have a better name. I think we can also consider removing the flip param, and just let the user flip the matrix with a transform later.

Fix bug in look_at

Use the up vector to determine turn direction

Add look_at_stable

Matrix2::look_at calls look_at_stable

Workaround rust-lang/rust#41478. 
Replace all `impl .. for Struct<<A as Angle>::Unitless>` by
`Struct<A::Unitless>`. This allows -Zsave-analysis to work on nightly, and
I think this is more readable too.

240559b941 iter traits: impl iter::{Sum, Product} 
This adds `Sum` trait for the `MatrixN`, `VectorN`, `Quaternion`
structures and the `Product` trait for `MatrixN`, `BasisN` and
`Quaternion`.

It also add constraints on the `Rotation` and `SquareMatrix` to require
the `Product` trait and `VectorSpace` to require `Sum`.

2cd6f402df Move the dot method onto EuclideanVector 
The Vector and EuclideanVector traits roughly line up with the concept of vector spaces and inner spaces respectively. It makes more sense to group `dot` with the other methods that depend on it.
