Implement a Matrix4 class

A 4x4 matrix that implements matrix multiplication and multiplication by
scalars. Some unit tests too, to test that this stuff works.

Add Camera::LookAt
...
This is identical to the POV-Ray look_at keyword for cameras. In fact, I stole the code almost directly from them… It's super handy for panning and tilting the camera towards a particular point, and saves me having to do dubiously accurate direction vector calculations by hand.
I still need to figure out what exactly this math is doing.

Add Write methods to scene objects
...
Write methods are polymorphic, overridden by subclasses. There is a single operator<< for Objects that calls the right Write() method for the object. Neat.

Move slab intersection to Box::IntersectSlab

Makes it easier to debug because I don't have to change things in three places.
This change also includes the fix! The swap was the problem. I didn't have the optimization right. I'll have to go back and figure it out.
