Rect collision detections don't work well based of the changing size of documents rectangles

I will use Collision Detection, to make sure not rectangles overlay each other.

Another solution is providing a bigger repulsion if the node area is large.

Make my own Collision Detection, instead of using the basic one. But the basic radius one should also work!!!!

[yalibian]

Should test the radius based on x, y, instead of doing it based on unfixed bug

[yalibian]

Fixed the bug using: forceCollide.initialize(simulation.nodes());
