This note will hopefully improve in future with all the errors found
by the readers corrected and the parts rewritten which are still
not explained clear enough. I have not choosen a specific phase convention,
since without a phaseconvention, it is much easier to decide which
parameters can be measured and which parameters depend on a specific
phaseconvention. It was also not necessary to start with assuming small
violation. The basic formulae do not become more complicated.
All calculations are based on the strangeness eigenstates 
and
