用于android手机中陀螺仪姿态角检测，包含了KF算法。
可以用于各种手机姿态、倾角检测。
// Integrate around this axis with the angular speed by the timestep
// in order to get a delta rotation from this sample over the timestep
// We will convert this axis-angle representation of the delta rotation
// into a quaternion before turning it into the rotation matrix.
