1st pass implementation

Initial Framework
  -makefile
  -spawn 3 threads
     *temp reader
     *output controller
     *data server
  -main logic loop

Add libbcm2835 library

GPIO output working and added default hardcoded settings.

Add 1wire temp sensor reading
Seperate timer signals and add system_settings

  Temp conversion is broken
Add Eagle schematics

  Also rearrange files
V1.0 of relay board
Add HW tracking info file
Expand temp readings, start implenting logging to SQL database
Version 1.1 of expansion board

  * Rotated header 180 so expansion board sits over Rpi
  * re-wired relays to switch GND via darlingtons
  * Added optional SMD LEDs to relays 1-6 for testing
Version 1.1b of expansion board

  * v. 1.1 failed batchpcb DRC.
  * Re-did layout by hand
  * Added larger solder pads on relays
Version 1.1c of expansion board

  * v. 1.1b failed batchpcb DRC (SFE DRC rules were the problem)
Basic logging implemented

  * Log to db
  * Moved from mysql to sqlite3 for performance
Cleanup for migration to github
