findChild	find child nodes
findSibling	find sibling nodes
shareNode	find the first node shared in the paths of nodes to the root
unionLeaf	find the union of descendant leaves
trackNode	track nodes by adding alias labels to a phylo object
isLeaf	test whether a node is a leaf node
showNode	print out nodes of a tree
addLabel	label nodes of a tree
