MS_rotEuler arguments shape

[andreww]

MS_rotEuler (and presumably the other rotation functions) allows row vectors for the three sets of angles but not column vectors. When using my scripts aimed at the VPSC code this means I need to do:

MS_rotEuler(C, eulers(1,:)', eulers(2,:)', eulers(3,:)')

Should handle this case cleanly in the code.

When this is fixed, we should also deal with the use case in MS_rotRandom and test_MS_rotRandom
