Yeah, I would have preferred to start with something a little simpler,
but I didn't have much choice; I have to make these boards now.

I took the resistor from the RCL library, and then made the capacitor,
inductor, and LED off of the same package.

After a little while, I got tired of searching for the parts I needed
in the libraries and decided it would be faster to make them myself.
I usually used a premade package spec and just drew the symbol, if it
was something standard.

I was thinking about using the $33 each special from Advanced
Circuits, but I may just get a plain board so that I can get them
faster; there aren't too many underside connections.
