Notes

The children property will be dynamically populated when children Nodes declare a Node as parent.

Examples

>>> root = Node(1, "root", "root")
>>> child = Node(2, "child", "child_rank", root)

>>> child.taxid
'2'
>>> child.rank
'child_rank'
>>> child.name
'child'

>>> child.parent
Node object:
        Taxid: 1
        Name: root
        Rank: root
        Parent: None

>>> root.children
[Node object:
        Taxid: 2
        Name: child
        Rank: child_rank
        Parent: 1]
