Energy function for attraction between two adjacent vertices.
Implements an energy function that simulates attraction between two adjacent vertices. There is an optimum distance where the energy is zero. The energy grows quadratic with the difference to the optimum distance. The optimum distance between two adjacent vertices depends on the size of the two vertices.
