//! Mag is a library for dealing with units of measure.  Magnitude!
//!
//! ## Highlights
//!
//! * Easy to understand and use
//! * No external dependencies
//! * Fast compile time
//! * Units are not discarded when creating quantities
//!
//! ## Example
//!
//! ```rust
//! use mag::{length::{ft, m, mi}, time::{h, s}};
//!
//! let a = 1.0 * ft; // Length<ft>
//! let b = a.to::<m>(); // convert to Length<m>
//! let c = 30.0 * s; // Period<s>
//! let d = 60.0 / s; // Frequency<s>
//! let e = 55.0 * mi / h; // Speed<mi, h>
//!
//! assert_eq!(a.to_string(), "1 ft");
//! assert_eq!(b.to_string(), "0.3048 m");
//! assert_eq!(c.to_string(), "30 s");
//! assert_eq!(d.to_string(), "60 ㎐");
//! assert_eq!(e.to_string(), "55 mi/h");
//! ```
//!
//! ## Room For Improvement
//!
//! * Small set of quantities and units implemented
//! * Quantities are f64 only
//!
