//! A convenience wrapper and needed parsers to work with ROOT's
//! `TTree`s. A Tree may be thought of as a table where each row
//! represents a particle collision. Each column may contain one or
//! several elements per collision. This module provides two Iterator
//! structs in order to iterate over these columns (`TBranches` in
//! ROOT lingo).
