Feature request: cophylo of more than 2 trees

[alexweisberg]

Hi, Phytools is great and I use it a ton for my research. I really like the cophylo function for displaying incongruencies or recombination between sets of genes. I was wondering if it would be possible to extend it to plot a set of more than 2 trees? I.e. 3 or more trees, all facing the same direction, with tips linked. Similar to figure 1 of this paper: https://journals.plos.org/plospathogens/article?id=10.1371/journal.ppat.1006466. I'm guessing it would be difficult to rotate clades to be optimized across many trees though...

Thanks!
