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:

• geom::Mesh
• geom::SmoothTriangle

which themselves rely upon:

• geom::properties
  • Collide
  • Emit
  • Trace
  • Transformable
• geom::shape
  • Cube
  • Triangle
• geom::rt
  • Ray
  • Side
• 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 186267f 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:

• geom::properties
  • Collide
  • Emit
  • Trace
  • Transformable
• geom::shape
  • Mesh
  • SmoothTriangle
  • Cube
  • Triangle
• geom::rt
  • Ray
  • Side
• 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.
