//! Clustering algorithms.
//!
//! ![A cluster](http://upload.wikimedia.org/wikipedia/commons/e/e1/Cassetteandfreehub.jpg)
//!
//! This crate provides generic implementations of clustering
//! algorithms, allowing them to work with any back-end "point
//! database" that implements the required operations, e.g. one might
//! be happy with using the naive collection `BruteScan` from this
//! crate, or go all out and implement a specialised R*-tree for
//! optimised performance.
//!
//! Density-based clustering algorithms:
//!
//! - DBSCAN (`Dbscan`)
//! - OPTICS (`Optics`)
//!
//! Others:
//!
//! - *k*-means (`Kmeans`)
//!
//! [Source](https://github.com/huonw/cogset).
//!
//! # Installation
//!
//! Add the following to your `Cargo.toml` file:
//!
//! ```toml
//! [dependencies]
//! cogset = "0.2"
//! ```
