Me likes the looks of this.

I added a bit to the 'layo' builder that eliminates repeat coordinate entries. I went from over 100 coordinates down to 8 on the bevel buttons! Wow. Also some bug reduction concerning the 0th element in 'layo's. I had just skipped it and wasted the memory in the program, though it didn't affect the final output. But it's less likely to cause a bug without that.
