General Purpose Hierarchical Data Structure
Create tree structures from hierarchical data, and traverse the
tree in various orders. Aggregate, cumulate, print, plot, convert to and from
data.frame and more. Useful for decision trees, machine learning, finance,
conversion from and to JSON, and many other applications.
