warning : the main difference between the "cokus" version and the
original version is the use of "*a" coding instead of "a[i]". We know
that the interest of this trick is platform and compiler dependent. So,
the implementer of this class should use the preprocessor flag
introduced by Todd or Blitz++ array classes and their iterators. For
example on my MacOS powerPC box with the compiler Codewarrior Pro 4, the
speed difference between these two versions is very small, with a small
advantage to the original one.
