A generic initializer. 

Sets the maximum neighbor distance to its default, and the component membership to -\/1 (no component).

This is called when a node is finished initializing. 

We set the maximum neighbor distance to its default, and if possible, we set the component membership of the node (if it has only one point and no children).
