Find most recent ancestral node for each tip

[Santi Montero]

Hi,

I noticed that the function 't.get_common_ancestor' can give you the first common ancestor of a given set of nodes. However, in my case, I would like to find for each tip in a tree which is its corresponding ancestral node (the node that produced the most recent split). Would that be possible? 

Thanks! (and sorry if this is a very basic question, I am relatively new to ETE3)
