RooGraphSpring:                                                            

The spring class is a subset of node class and a spring can only be created
if there are two nodes to connect it to. It is not drawn to the canvas, but
is used to determine the energy of each node and thus can be used to reduce
the energy of the node/edge system to its lowest possible value.
