Added changes to test structures. Fixed Comb insulation with thick wires, added parameter to test_ic for gap between pads. Note: in comb_test, wire_gap is the distance between the zig zags, not the distance between a wire and the comb wire next to it. If wire_gap and wire_width are the same value, the comb wires will touch the zig zag wires
