Extract parent and all children from a Phylo object
Source:R/parentCombinations.R
getParentPhylo.RdThis function takes in a `phylo` object or a `treekoR` result from the
getClusterTree function, and converts its into a
named list of each and children to input into
parentCombinations.
Note: Parent populations with one child will be pruned. Make sure to
include this cell type in the `all` vector when using
parentCombinations to ensure this cell type is included
in pairwise calculations.
