Current fork: Basic Adafruit Trinket NAZA LED Adaptation
Version: V1.0 June 14, 2014
Author: El Guano on rcgroups.com, phantompilots.com
Description: This version is modified to the Adafruit Trinket, particularly
the implementation posted at
http://www.rcgroups.com/forums/showthread.php?t=2144784#post28061982.
It is simplified from the original to save RAM and flash space; I also
didn't need RX-based controls or switchable animation modes, just basic
orientation and NAZA mimicry.
