Circular Loom Generator

This was inspired by https://www.thingiverse.com/thing:13316 & https://www.thingiverse.com/thing:2105183 but I didn't list it as a remix because I rewrote the code from scratch since I was getting mesh errors from the other versions and I didn't think all the sine and cosine calculations were necessary. The other code could take as much as 6 minutes or longer to render if you change more than one parameter at a time and my version averages 1.5 minutes or less since the math operations are simpler. I also did some of the division calculations outside the loops so they don't have to be done more than once.

In this version, the side post always prints without a knob. I also wanted the posts to always be round on the ends even if they are printed without knobs so I used a hull() of two spheres to make the posts. Last, but not least, I
