[Biococoa-dev] Subclass organization

[Charles PARNOT]

I vote for putting it in 'initializeSymbolRelationships'.
Oups, actually, don't we have a reference count, then?
We don't release complement in the dealloc, do we?
Yes, we do!
Well, we should not, because we are not retaining complement. And we should not retain. This is a case where we want a weak link. So we should not release it (did I already say that?).
I know it does not really matter because dealloc is probably never called and these objects never die, but well...
