 * This matrix is used in the relationships qd = 1/2*L^T*omega and
 * qdd = 1/2*L^T*alpha' - 1/4*omega'^2*q, where omega'/alpha' are the angular
 * velocity/acceleration of a rigid body in the body frame and qd/qdd are the
 * first/second time derivatives of the Euler (unit quaternion) parameters.
 * 
 * The matrix L is defined as:
 * -e1  e0  e3 -e2
 * -e2 -e3  e0  e1
 * -e3  e2 -e1  e0
