0Ω resistors don't work

[gunar]

IMHO they should act like simple wires.

This project looks awesome! Kudos! :D

Thanks!

Yes, they should.

Unfortunately the implementation is a bit more complicated than that. The circuit is modelled in terms of conductance, which is the inverse of resistance. Calculating the inverse of 0Ω means a division by zero. For this reason, wires are modelled as zero-valued voltage sources, rather than 0Ω resistors.

I'll need to either:

1. not allow users to set resistors to 0Ω
2. allow them, but put in a special case for 0Ω

I tend to use this as a reference. It seems he chose option 1. I think option 2 is better from a UX point of view though, users kind of just expect this to work.
