//! alg-grid
//! 
//! `alg-grid` is a collection of helper functions for
//! 2D and 3D grids, including Dijkstra's and A* algorithm.
//! 
//! These functions are implemented using this [website](https://www.redblobgames.com/pathfinding/a-star/implementation.html)
//! as a reference. Other functions came from the `bracket_lib` crate.
//! 
//! This crate does not require a standard library.
