//! Automatically derived typed Unit system with conversions.
//!
//! # Example
//!
//! ```rust
//! use unit_system::prelude::*;
//!
//! #[derive(Unit)]
//! pub struct Meter(pub f32);
//! #[derive(Unit)]
//! pub struct Inch(pub f64);
//!
//! // we can convert between any `Unit`s whose bases define BaseIntoBase
//! impl BaseIntoBase<Inch> for Meter {
//!   fn convert_base(self) -> Inch {
//!      Inch(self.0 as f64 * 40.)
//!   }
//! }
//!
//! // CMeter, DMeter, HMeter, NMeter... have been automatically built
//! let centimeters: CMeter = CMeter(3.);
//! // the same for inches (non-SI units would require manual impls of Unit)
//! let kilo_inches: KInch = centimeters.convert_outer();
//!
//! // KInch{ 0.012. }
//! println!("{:?}", kilo_inches);
//! assert!(f64::abs(kilo_inches.0 - 0.0012) < 1e-7);
//! ```
