Implement module: geom

[FreddyWordingham]

Ray-tracing structures and traits.

My initial objective for this is to implement enough to implement the wavefront module and get basic .OBJ file loading in place for geometry / mesh loading.

To accomplish this, I will need to port the following dependencies in the geom module:

• [x] geom::Mesh
• [x] geom::SmoothTriangle

which themselves rely upon:

• [x] geom::properties
  • [x] Collide
  • [x] Emit
  • [x] Trace
  • [x] Transformable
• geom::shape
  • [x] Cube
  • [x] Triangle
• [x] geom::rt
  • [x] Ray
  • [x] Side
• [x] ord::list::az::greek

So, my objective is to port these primitives across to support the implementation of the wavefront module. I note that these are likely to depend upon primitives from math, such as Pos3 whose name / implementation may have changed between codebases.

As of commit 186267fb38f8ba17bf9fb9eb2f282f8779e2016b I have migrated the modules that I mentioned in the previous commit. Now I just need to add documentation and unit tests for these libraries.

To keep track of this progress:

• [x] geom::properties
  • [x] Collide
  • [x] Emit
  • [x] Trace
  • [x] Transformable
• [ ] geom::shape
  • [ ] Mesh
  • [ ] SmoothTriangle
  • [ ] Cube
  • [x] Triangle
• [x] geom::rt
  • [x] Ray
  • [x] Side
• [x] ord::list::az::greek

I have done a a first pass at most of the documentation and unit tests in this module, however I need to now add the unit tests for each of the implementations for the geom::properties and geom::rt traits.
