Here is a debugged version of mylife, which cloned life2.py to
use a class for turtle-ing. Note the difficulties at the
end of the code -- ontimer(fun, delay) calls for a zero arg
function, so draw() cannot be inside the class. Greatly annoying.
But now we know.

mylife3.py is a suitable example, I think. If cleaned up to
standards. I noticed there is a curses life.py example, which
is very interesting and fun, but mylife3.py is more fun...and
it has 2 different board topologies! And
it would make a very good test program. Note that it sets
the random seed which establishes the Cell patterns, so a
test ought to be repeatable, at least on a given machine.
I plan to use mylife3.py instead of a space heater this winter :)
