P0-A2: Part 438: Procedural Structure Generator

I have added the ability to randomly generate more complex structures, etc, to the random generator.

The issue now is collision detection. I can create and place simple 2D objects reasonably well, and the overall shape of the structure should look ok if I add 3D interiors instead of 2d objects.

The problem is that despite several attempts at collision detection, I still can’t reliably position objects so that they don’t intersect.
