Compute the weighted average of all of the quaternions given in <code>qs</code> using the specified interpolation factors <code>weights</code>, and store the result in <code>dest</code>.
@param qs
the quaternions to interpolate over
@param weights
the weights of each individual quaternion in <code>qs</code>
@param maxSvdIterations
the maximum number of iterations in the Singular Value Decomposition step used by this method
@param dest
will hold the result
@return dest
