//! Tree views, as Pele's src/diagrams/treeview reads and draws them: a preprocessor that reads
//! a tree drawn with box-drawing characters as one indented, a tokenizer and a parser that
//! read what Mermaid's Langium grammar reads, a database that nests the entries by their
//! indentation, and a layout of a row to an entry.
