rubytree 0.8.2

RubyTree is a Ruby implementation of the generic tree data structure. It provides a node-based model to store keyed node-elements in the tree and simple APIs to access, modify and traverse the structure. RubyTree is node-centric, where individual nodes on the tree are the primary compositional and structural elements. This implementation also mixes in the Enumerable module to allow standard access to the tree as a collection.
