V-slot clip

I wanted a way to attach things to vslot without sliding in a bolt. Basically, a spring-loaded clip for 2020...
Having done that, I'm working on things that use the clip:

• - a variety of plates that circuit boards can be attached to, and then clipped onto v-slot. If you've ever seen a DINrPlate for the Pi (DINrPlate), that's what I had in mind. I've got plates designed for the Pi3B+, arduino UnoR3, the Big Easy Driver (Big Easy Driver stepper motor driver)
• - I've got the beginnings of a terminal block for attaching wires. You'll be able to attach 2 wires, but the blocks will be gang-able to give you larger terminal blocks.
• - A python program that generates new plates from some XML.
• - a twist-lock mechanism that will allow you to quickly attach two pieces of extrusion in seconds.
• - a different twist-lock to quickly&easily lock a clip in place so that it doesn't slide around.
