 // == Create the smaller spheres first then add the larger spheres round them
 // The larger spheres are created from a number of smaller boundingBoxes
 // The larger spheres are centred on the middle of the grid of the smaller boxes.
 // Create all the smaller boxes to be an exact division of roughly the size of
 // the smaller box we want.
 // Fill those smaller boxes with triangles
 // Remove any that are empty
 // Calculate the positions of the larger spheres
 // Convert the smaller boxes to sphere
 // Work out which smaller spheres fit in to which larger spheres
 // Remove any empty larger spheres.
 // The result is likely to have overlapping smaller spheres that stick out
 // of the larger spheres.
 // This overlap sometimes causes undesirable bouncing when colliding.
 // There is a separate function that should be run after the smaller spheres
 // have been edited that better fits the larger spheres with no overlap.
