A Small Example

import quadtree

type Box = tuple[x, y, width, height: int]
    ## This represents whatever type you want to store in the tree

var tree = newQuadtree[Box]()

tree.insert( (x: 1, y: 1, width: 5, height: 4) )
tree.insert( (x: 2, y: 3, width: 5, height: 5) )
tree.insert( (x: 19, y: 4, width: 3, height: 1) )

# Grab all the elements that are near (2, 2)
echo tree.fetch(2, 2)
