Design notes
* up to 3 DL1414s
* ICSP
* Optional 4.5v relay
* optional mosfet OR transistor 12v drivers, four of these
* 7805 socket
* extra power/ground points for capacitor smoother
* placements for up to 10 LEDs (2 resistor packs)
* placements for 1 (or 2 or 3?) RGB LEDs (using same as LEDs)
* Header with all the ios, maybe paired for LED use.

RB0-RB6: DL1414 D0-D6
RB7    : DL1414 A WR'  // CENTER SPOT


RA6-RA7: DL1414 A0,A1
RA3    : DL1414 B WR'  // LEFT
RA4    : DL1414 C WR'  // RIGHT

RA0 : preferred analog input.
RA1-RA4 : MOSFET/Transistor drivers
RA5 : input, with onboard pullup

RA0-RA4 : main 5 LED outputs

RB0-RB6 : preferred inputs (has weak pull-up, as long as RB7 stays high wont bother DL1414s.
