One minor correction here. The length of TinyVector is not strictly limited
to 11. However, the set of constructors that take initial values for each
TinyVector element ends at 11. This is essentially just an issue of
stamina; one could add more constructors. But the "Tiny" classes are meant
only for small vectors and matrices of fixed size. The Vector and Matrix
classes are container classes more like Array, but they have special
operations defined for linear algebra that are not applicable to a general
Array class.
