Construct from a non-zero vector (x,y,z) and an angle.
Precondition: the Vector needs to implement x(), y(), z(), and unit()

Construct given a pair of pointers or iterators defining the beginning and end of an array of four Scalars, to be treated as the x, y, and z components of a unit axis vector, and the angle of rotation.
Precondition: The first three components are assumed to represent the rotation axis vector and the 4-th the rotation angle. The angle is assumed to be in the range (-pi,pi]. The axis vector is automatically normalized to be a unit vector
