collision detection not working with clustering

[hdngr]

alchemy.conf = { 
     collisionDetection: true,
     clustering: true
}

Loosened up the clustering a good bit so it doesn't look bad at all, but the collision detection in general isn't working due to a null "quad" parameter being passed into collide in layout.coffee . Moving to a different thing right now, but leaving this comment for when we come back to it.
