Deep copy (clone) and merge on a Tree

[kevboy]

We could write our own methods to do the mentioned operations but I was just wondering...

1) Is there a quick way to do a deep copy of a Tree?

2) Is there a quick way to do a merge (union excluding duplicates) of two or more Trees?

Thanks for your help!

1) not a one-shot method, no, but you can share Trees between components in some cases

2) not a one-shot method, but list-oriented accessors like getOpenList() make it pretty easy to use the Java built-in Collections stuff to do this.
