SSR module version PCB, RevB Fixed bugs in RevA of the SSR module version PCB: Issue #40: Must drive SSR1 and SSR2 from separate Arduino pins. In the RevA design, there is a path from +5V to GND through the two SSRs, which can cause destruction of the SSRs and the bleed resistor. Issue #41: Resistor R3 must be connected precisely to the shunt (+) end pad so it doesn't see the voltage at some point in the sea of copper that is the LOAD_CAP- net. This resulted in current measurements that were too high, and depended on whether the current was flowing from SSR3 or from the load caps. Issue #41: The path from the shunt (-) end pad to the screw terminal pads must be a stub off the GND plane so that when current is flowing, the GND plane doesn't see a voltage drop. Also, the linkage between this stub and the GND plane must be made at the shunt (-) end pad so the voltage of the GND plane is equal to the voltage at the (-) end of the shunt. Also swapped the pads for the bypass diodes for layout reasons related to making the current-carrying part of GND a stub.

PCB reorg + add SSR version Reorganized PCB files so board type is at the top level, and each has EAGLE and Gerber folders under it. README file has description of each one, plus status and ordering info. Added files for the SSR version.
