Implemented parsing of actuation input & output of actuation
Added output of comapss, ahrs, & gps back in.  commented out declination... preferring to do it in higher level software.
Added trigger A2D on port 0
Added offet values onto raw magnetomer value reporting
Removed redundant division by 100 on GPS speed
In AHRS, removed reporting of gyro drift.  Report Gyros & Accels instead.
Added a safety timeout for throttle.
added 3 second timer... so that the lid can be closed
set console UART to 57600.  changed the way TOGGLE_CHANNEL is read
moved toggle pin to avoid mechanical interference.  servo & throttle input from serial now come in as raw pwm (no scaling needed). Set baud rate to 57600, to permit use of radios as debugging tool
re-factored throttle output
Actuation output limited to 10 hz
Added Pixy library.  Copied from their repository... still pristine.
Replace Arduino calls w/ HAL to get Pixy UART working in Ardupilot
Added intial instatiation of pixy class.  Only reports number of blocks for now.
