Compare two clonal evolution trees to see if they differ assuming excluded nodes are already excluded, labels are ordered
Return F if they are different, T if they are the same
compare.clone.trees(v1, v2, compare.seeding.models = TRUE)
clonal evolution tree data frame 1
clonal evolution tree data frame 2
if true, match all sample status (presence/absence/founding) at all nodes to make sure clonal seeding between samples are preserved.
