//! Financial utilities and helper functions
//!
//! This module provides common utilities, mathematical functions, and helper tools
//! used throughout the finance module.
//!
//! # Modules
//! - `math`: Mathematical utilities for finance
//! - `calibration`: Model calibration tools
//! - `simulation`: Simulation utilities and random generators
//! - `financial_utils`: Day count conventions, calendars, and compounding
