## General principles

* Objects interact with the world outside the program (_e.g._ I/O)
* Objects contain state
* Modules provide traits/behaviors/information common to multiple objects (_e.g._ logging)
* The Leeroy::App namespace defines the CLI (commands, runtime configuration)
* The Leeroy::Data namespace defines the persistence layer
* The Leeroy::Task namespace defines the application's capabilities
* The Leeroy::Helpers namespace contains only helper modules, no class definitions

## Hierarchy

classes are marked with `*`
