//! # Graf Karto cartographer
//!
//! ### What is it exactly
//! Graf Karto is a table top role playing game (TTRPG) map creation tool that is optimised for real
//! time map interaction.
//!
//! ### Motivation
//! While there are certainly many TTRPG map creation tools for single user and multi user available
//! online and on the market, we felt that most of them lack features or are to unwieldy to seriously
//! consider for real time dungeon drawing, say for instance when drawing a map for an old school
//! revival style game. This is why Graf Karto is optimised for speed above pretty graphical features.
//! The aim is for the user not to have to think much about how they are going to achieve what they are
//! doing and how they are going to make it pretty, but should just be able to *do* it, to have time to
//! worry about other things. This does not mean that all maps created should visually be equivalent to
//! a steaming pile of hot garbage, but if the visuals should try to get in the way, usability and speed
//! takes precedence.
