SPLIT ZONES HAVE BEEN INTRODUCED!!!
Click the draw button to start drawing. Left click and drag to highlight an area on the canvas. Let go to finish. When the **center** of your disc goes inside the rectangle it will trigger a split. Splits are not per map yet but do save through sessions. Currently the only way to remove splits is to use `localStorage.clear()`. (Advanced users can parse the JSON string, edit it, and set back to localStorage if they wish. Try not to cause an error).
