Description

**RubyTree** is a pure Ruby implementation of the generic `tree data structure <http://en.wikipedia.org/wiki/Tree_%28data_structure%29>`_. It provides a node-based model to store named nodes in the tree, and provides simple APIs to access, modify and traverse the structure. The implementation is *node-centric*, where individual nodes in the tree are the primary structural elements. All common tree-traversal methods (`pre-order <http://en.wikipedia.org/wiki/Tree_traversal#Pre-order>`_, `post-order <http://en.wikipedia.org/wiki/Tree_traversal#Post-order>`_, and `breadth-first <http://en.wikipedia.org/wiki/Breadth-first_search>`_) are supported. The library mixes in the `Enumerable <http://ruby-doc.org/core-1.9.3/Enumerable.html>`_ and `Comparable <http://ruby-doc.org/core-1.8.7/Comparable.html>`_ modules to allow access to the tree as a standard collection (iteration, comparison, etc.). A `Binary tree <http://en.wikipedia.org/wiki/Binary_tree>`_ is also provided, which provides the `in-order <http://en.wikipedia.org/wiki/Tree_traversal#In-order>`_ traversal in addition to the other methods. **RubyTree** supports importing from, and exporting to `JSON <http://flori.github.com/json>`_, and also supports the Ruby's standard object `marshaling <http://ruby-doc.org/core-1.8.7/Marshal.html>`_.
