design sheet metal products using TypeScript

• https://github.com/villagekit/gridjig-fold
• FreeCAD examples: https://wiki.freecad.org/SheetMetal_Examples
• Sheet metal design openscad/openscad#1459

two possible approaches:

1. describe 2d sheet + folds directly

• pros: easier to implement
  • 2d sheets and folds are there directly
  • imagine not too difficult to generate 3d view from 2d description
• cons: harder for designer

2. describe solids + algorithmically generate folds

• pros: easier for designer
• cons: harder to implement
  • unfolding algorithms are hard computer science
  • 3d description might not be possible to create with folds, and might not match actual folds
