[WIP] Parametric Cherry Library

This OpenSCAD library intends to be able to generate cherry profiled keycaps intended for 3D printing: keycaps will be printed vertically to encourage better print quality

Goals for the future:

• FIX weird ledge as a result of hull() (consider chaining hull()'s)
• Create stems
• Entertain the idea of generating separate stems for better 3D printing
• Add support for custom legends
