Yapa

"Yet Another Paparazzi Autopilot".
This autopilot was not designed to replace any other, but just as another version of the same and is posted here just in case it might be useful to anybody. The Yapa is very similar to the Twog_v1 but has standard 100mil headers for direct standard servo connections, and has the xbee on the board itself.
