/**
 * Not happy with this solution, but computing the angular velocity of the average orientation
 * appears to be rather complex.
 * 
 * The variables are the following:
 * <ul>
 * <li>The frame one has an orientation q1 and an angular velocity &omega1.
 * <li>The frame two has an orientation q2 and an angular velocity &omega2.
 * </ul>
 * This mid frame has an orientation qi located in the middle of q1 and
 * q2. It is calculated as follows: 
 * qi = q1 (q1-1q2)0.5
 * 
 * When comparing against finite difference, it is clear that: &omega;i &ne; 0.5
 * (&omega;1 + &omega;2).
 * 
 * 
 * Therefore, the time-derivative of the equation used to compute qi needs to be
 * calculated using quaternion differential calculus. However, I keep getting stuck at computing
 * the time-derivative of a quaternion raised to a power: 
 * 
 * <pre>
 * d q(t)&alpha;
 * ------ = ???
 * dt
 * </pre>
 * 
 * where in our case &alpha; = 0.5.
 * 
 * 
 * So as a workaround, using the known angular velocities, qi is evaluated at
 * t+&Delta;t and the angular velocity computed from finite difference. This should behave better
 * than simply using {@code NumericalMovingReferenceFrame} which does not take into account the
 * angular velocities of the two input frames.
 *

// Test against Quaternion multiplication

// Test against RotationMatrix multiplication

// delta2 = log( exp(-wa*T/3) * qa^-1 * qb * exp(-wb*T/3) )

// If epsilon >= Math.PI, any pair of two quaternions will be equal
