get_trees_list: extract all phylogenetic trees in ape format
Description
extract all phylogenetic trees in ape format
Usage
get_trees_list(nexml)
Arguments
nexml
a representation of the nexml object from which the data is to be retrieved
Value
returns a list of lists of multiphylo trees, even if all trees are in the same `trees` node (and hence the outer list will be of length 1) or if there is only a single tree (and hence the inner list will also be of length 1. This guarentees a consistent return type regardless of the number of trees present in the nexml file, and also preserves any heirarchy/grouping of trees.
