Example usage

// create the quadtree

// this tree is faster but constrained to the initial bounds 
var quadTree = new QuadTree<string>(x: 0, y: 0, width: 2000, height: 2000);

// this tree is a bit slower but has no constrictions in space
var dynamicTree = new DynamicQuadTree<string>();

// add some objects to the tree
for(var x = 0; x < 2000; x += 20)
{
    for(var y = 0; y < 2000; y += 20)
    {
        quadTree.Add(x, y, 10, 10, "whatevs");
        dynamicTree.Add(x, y, 10, 10, "whatevs");
    }
}

// find some objects
var objectsInArea = quadTree.FindNode(500, 500, 50, 50);
var otherObjectsInSameArea = dynamicTree.Add(x, y, 10, 10, "whatevs");

// remove an object
quadTree.Remove(objectsInArea[0]);
dynamicTree.Remove(objectsInArea[0]);

// clear the tree
quadTree.Clear();
dynamicTree.Clear();
