<DD>Splits a node into two based on the midpoint value of the dimension 
 in which the node's rectangle is widest. If after splitting one side
 is empty then it is slided towards the non-empty side until there is 
 at least one point on the empty side. The two nodes created after the 
 whole splitting are correctly initialised. And, node.left and 
 node.right are set appropriately.
