I am here again, I finally got to write the "collapse nodes" function and have a
couple of questions.

In order to collpase any node $node, I first have to get the parent
which I can do as $parent=$node->ancestor

and then the children as:
@children=$node->get_all_Descendents (or should I use each descendent?)

Then before deleting $node I have to assign all its children to $parent,
and here is where I am kind of confussed.
Can I use the add_Descendent function for this?
I've been tryig to write something like this:
foreach $child (@children){
but this doesn't work and I think it is because I don't have any idea of what I
am doing
any suggestions?
