P0-A2: Part 497: Refactoring, Testing

I am still working on testing the functioning of the system over very long distances.

It is mostly functional, but there are some serious issues that occur in some cases.

When placing objects at precise locations, (such as placing a building, etc, on the surface of a planet) there are precision issues. There are also problems with the paging system that I have implemented to enable/disable objects depending on their distance from the camera.

I will need to find a way to place objects on the actual terrain chunks of the planets, similar to what I am doing with trees and cities already. The problem with this approach however is that these objects are only created when the player is close to the planet, so it would not be possible for the player to navigate to these objects from long range.
