Dendrite Growth with Cracks

Dendrite growth using d3 quadchart nearest neighbor search. A point is chosen at random and joined to its nearest neighbor. Each node keeps track of the node to which it was adjoined via a parent reference. As each node is attached the child count of each parent in the chain is incremented. The child count is used directly to determine rendering width of lines between nodes.
