cli-tree 1.0.0

This library can be used to build a tree structure, and render or print it like an ASCII graph. It can be used to implement a directory tree printer or something like that. Example: require 'cli-tree' tree = TreeNode.new("root", [ TreeNode.new("foo", [ TreeNode.new("bar"), TreeNode.new("baz") ]) ]) puts tree.render # or simply tree.print Output: root └── foo ├── bar └── baz
