Re: Copy and initSeed

[Benedikt Stefansson]

Thanks to Roger for clarifying the 'copy' issue. 

After experimenting with several solutions I settled on a fairly
customized set of 'copyFrom' and 'copyTo' methods in the agents in
question. I doubt that the solution would be transparent or portable,
but I would be glad to explain how it works if someone else runs into a
similar problem.

Essentially the solution was to use clone=[Class createBegin: aZone] to
get an instance of the desired class, and add a method -copyTo:
(id)clone to the class that knows about all the necessary stuff that has
to be initialized and copied over. 

This runs against Roger's suggestion that -copy messages adher to the
copy: aZone protocol, but in this case the Zone stuff was taken care of
before the copy method was to be invoked.

-Benedikt.
