The TinyVector class provides a small, lightweight vector object
whose size is known at compile time. It is included via the header
<blitz/tinyvec.h>.
Note that TinyVector lives in the blitz namespace, so you will
need to refer to it as blitz::TinyVector, or use the directive
using namespace blitz;.
The Blitz++ Array object uses TinyVector internally, so if you
include <blitz/array.h>, the TinyVector header is automatically
included. However, to use TinyVector expressions, you will
need to include <blitz/tinyvec-et.h>.
