This is a first attempt at tracing an object with a sphere_sweep produced from a
non-random cube point cloud. Obviously needs a bit of work before it will be
useful for much.

Right now it kind of looks like the nasty wax-like icing on those wretched
little debbie/hostess cakes [no offense to those companies, just my personal
opinion..still...yuck].

Current issues:
1)    Inside() tests result in no points being usable (all eval as being
inside). Not sure how to reorient_trans() just a vector, as I think that macro
applies to objects. Intend to confirm. Currently consider reorient_trans() as a
possible fix until more information obtained.

2)    Obvious spiral due to method of point generation and array traversal.

3)    Need to pre-generate a spline of same type used in sphere_sweep for
intelligent object placement along said path, as well as ability to pre-evaluate
output of sphere_sweep for fitness and auto-modify to produce desired results.

4)    Finding a use for this. Solution seeking a problem.. Maybe pipes/greeble?
Who knows.

This image isn't particularly artistic, as I'm more interested in the logic of
solving the problem than I am much else, so...yeah.
