The starship hull generator code that takes a JSON config file and makes a hull out of it is now capable of creating a brand-new config file for the generated empires. That means the default 250 empires will have their own unique ships, no default/undefined shape. So, the next thing to do is take these configs and make similar versions for different classes. Then, followed by coding the actual shipyards in-game!
It took a while to detect/get rid of hull shapes that intersect themselves. But it is finally ready. I may add this into a new build of the Ship Flight testing program.
