*	I finished to implement nonlinear complementary filter on the SO(3).	Hyon Lim (Retina)	2013-05-29	1	-56/+120
\| \| \| \| \| \|	The previous problem was roll,pitch and yaw angle from quaternion. Now it is fixed. 1-2-3 Euler representation is used. Also accelerometer sign change has been applied.
*	Test flight has been performed with nonlinear SO(3) attitude estimator.	Hyon Lim (Retina)	2013-05-23	1	-111/+113
\| \| \| \| \| \| \| \| \| \| \| \|	Here are few observations: - When the system initialized, roll angle is initially reversed. As filter converged, it becomes normal. - I put a negative sign on roll, yaw. It should naturally has right sign, but I do not know why for now. Let me investigate again. - Gain : I do not know what gain is good for quadrotor flight. Let me take a look Ardupilot gain in the later. Anyway, you can fly with this attitude estimator.
