[izpack-devel] TreePacksPanel

[Vladimir Ralev]

Yes, leaf packages show their individual size, but parents show total 
size (their own + all childs transitively).

I have committed now my initial version in the trunk, which looks stable 
although there is still some undefined behaviour when child nodes are 
required but a parent node is excluded by other rules, I think I must 
re-write the PacksModel instead of wrapping it, but for now this will 
do. You can try it and let me know if you find something wrong. Thanks 
everyone.
