//! # Mathypad
//!
//! A smart calculator that understands units and makes complex calculations simple.
//!
//! This library provides the core functionality for mathypad, including:
//! - Unit-aware mathematical expression evaluation
//! - Comprehensive unit conversion system
//! - TUI application framework
//! - CLI interface utilities
