Changes as of 9/18/14
- SOMETHING HAPPENED.
 - A slight glitch in the reflection model seems to have been fixed (don't ask me how)
 - Rotation around the Y axis looks logical, X axis seems a bit iffy when the Y rotation != 0
 - Things seem to be going much better now!

- Added another set of constructors to RenderModes
- Fixed the setRenderMode() misplacement in GraphicsEngine.initialize()
- Added methods for relative X,Y,Z axes of a rotation (right, up, forward directions)
- Scaled the example mesh down halfway (to avoid clipping the render boundaries)
- Added some extra debug controls to the TestCamera

- VERY HAPPINESS COMMIT
