//! A collection of map generators.
//! Generators for dungeon type maps.
//!
//! The generators are implemented for the following types of maps:
//! * Dungeon maps
//! Generators can bu used directly or they can be combined with
//! `MapGenerator`s and `MapModifier`s
//!
//! * MapGenerators are use to create initial map.
//! * MapModifiers modify existing map.
//!
//! Example
//! ```
//! use mapgen::{MapFilter, MapBuilder, Map, TileType};
//! use mapgen::filter::{
//! CellularAutomata,
//! starting_point::{AreaStartingPosition, XStart, YStart}
//! };
//! use mapgen::geometry::Point;
