Description:

This module in an fully object-oriented implementation of a simple
n-ary tree. It is built upon the concept of parent-child
relationships, so therefore every Tree::Simple object has both a
parent and a set of children (who themselves may have children, and so
on). Every Tree::Simple object also has siblings, as they are just the
children of their immediate parent.

It is can be used to model hierarchal information such as a
file-system, the organizational structure of a company, an object
inheritance hierarchy, versioned files from a version control system
or even an abstract syntax tree for use in a parser. It makes no
assumptions as to your intended usage, but instead simply provides the
structure and means of accessing and traversing said structure.
