//! The rust side of the `dist/project-constants.json` file
//! 
//! ## Overview
//! 
//! This file contains a structure defining all data we want to load from the project constants file.
//! Feel free to add anything you'd like here, just make sure the relavant data is also written in the JSON file so the game doesn't crash.
//! You can treat these as constants. I just prefer storing this kind of data in JSON rather than hard-coding it in the program.
//! 
//! ## How this is loaded
//! 
//! Somewhere in `lib.rs`, a call is made to load this through the `asset_manager`. 
//! Its all already set up, so you shouldn't have to worry about the logistics.
