Test the logic gate PCBs

[jessehamner]

• Fab the OR, AND, NOR, and NAND gate PCBs
• order the components
• test that they work as expected
• ensure they don't draw too much current per gate
• build a composite gate like an XOR
• ensure that kids can solder the gates without difficulty

The AND gate works fine. Unfortunately, the VCC/GND pins are 0.05" off on each of the boards.. This has been fixed in the schematic and layout files.

All the CMOS boards work fine, including XOR. The AND gates may need one more revision.
