Quaternion IS-A vector, and is a special case of general n-dimensional space. The IS-A relationship is enforced with public inheritance. All member functions on vectors are applicable to quaternions.

Rep Invariant:

• norm = 1, for a rotation.
• position vector represented by imaginary quaternion. References:
