/*
 * koton.js
 *
 * A Tiled (https://www.mapeditor.org/) extension for exporting CyTube MMO format maps.
 *
 * Usage:
 * 1) Create a new map with two tile layers - "map" and "collision". On "map",
 * just draw the map, and on "collision" - with any tile - draw over the tiles
 * that the player shouldn't be able to pass through.
 * 2) When done, export the map as a 'koton map format (*.js)' file.
 * 3) Copy the contents of the newly generated file, then paste them into your
 * into your map's 'tilemap' key
