Key Gauge Generator

I needed a key gauge that wasn't already up in Thingiverse, so I took the opportunity to learn a little bit more OpenSCAD in the process.

It's not pretty, and I'm sure there are more elegant and parametric ways to do things, but this will enable me to print the key gauges I need. Maybe someone else can use it, too.

Root depths are in inches, so the script converts the depth list to millimeters.
