//! A low-dimensional linear algebra library, targeted at computer graphics.
//!
//! # Trait overview
//!
//! In order to make a clean, composable API, we divide operations into traits
//! that are roughly based on mathematical properties. The main ones that we
//! concern ourselves with are listed below:
//!
//! - `VectorSpace`: Specifies the main operators for vectors, quaternions, and
//!   matrices.
//! - `MetricSpace`: For types that have a distance function implemented.
//! - `InnerSpace`: For types that have a dot (or inner) product - ie. vectors or
//!   quaternions. This also allows for the definition of operations that are
//!   based on the dot product, like finding the magnitude or normalizing.
//! - `EuclideanSpace`: Points in euclidean space, with an associated space of
//!   displacement vectors.
//! - `Matrix`: Common operations for matrices of arbitrary dimensions.
//! - `SquareMatrix`: A special trait for matrices where the number of columns
//!   equal the number of rows.
//!
//! Other traits are included for practical convenience, for example:
//!
//! - `Array`: For contiguous, indexable arrays of elements, specifically
//!   vectors.
//! - `ElementWise`: For element-wise addition, subtraction, multiplication,
//!   division, and remainder operations.
//!
//! # The prelude
//!
//! Importing each trait individually can become a chore, so we provide a
//! `prelude` module to allow you to import the main trait all at once. For
//! example:
//!
//! ```rust
//! use cgmath::prelude::*;
//! ```
