//! easyenv
//!
//! The interface between an app and its environment variables. This library makes it easy to:
//!
//!   - read in strongly-typed environment variables.
//!   - load default environment variables from one or more files in an order that supports
//!     intentional overriding.
//!
//! Things that might want to move to another package :
//!
//!   - configure env logging
//!   - build conventions around system paths such that paths imported from environment variables
//!     respect pathing conventions.
//!
//! This library does not:
//!
//!   - handle app-specific conventions
//!   - care about servers or deployed environments (eg. "staging" vs "production")
//!
