children() returns the children of a node in a random order as given by 
the database, that may vary from one call to another.
sorted_children() returns the same children, but in a stable and 
reproducible order.

In your case, you can call any of these two methods, but on $tree (which 
is at this stage a GeneTreeNode).

The code to select subtrees of the appropriate clade should actually be 
the same as in previous releases. I think only the initial call to get 
the list of root nodes is different (+ the interpretation of the 
"Duplication" tag)
