PCB Design: Schematic, Parts, and Layout

[saltzmanj]

Initial design is complete and in the Google Drive folder. We need to put in some work deciding what connectors are used, both board-to-board and board-to-keys. Right now they are generic 1" pitch headers but that can easily be changed.

@MrBitSage @arlieu : I'm ready to send off the PCB designs. It would be awesome if you guys could spend like 10 minutes just double checking schematic and layouts for both the Signal Driver Board and the Octave Boards just to make sure I'm not missing something stupid.
