VectorAngle(<-from <-to) ->rotAngle

Returns the angle in degrees between from and to. The angle returned is always the non reflex angle between the two vectors - ie the smaller of the two possible angles between them and never greater than 180 degrees. NOTE: This routine does NOT work with 4 dimensional vectors. The 4th dimension will be ignored (treated as 0).
