fun with nested loops

interesting idea, thanks.

I unsuccessfully played a bit with a FSM, but there is a lot of data
that is passed around between the states and a lot of counting (like
trying a certain step n times), so the FSM turned out to be even more
complex. And I have to keep the code simple for non CS people to run
the actual experiment. The loops are kind of self-explanatory, this is
exactly how you would specify the experiment, even though I am really
hitting a wall at the moment.

Maybe I am really missing an obvious solution, because breaking out of
nested loops really doesn't seem like anything fancy. Fortran/c/c++/
Ruby/Perl all have that facility, even Java has named loops.
