public class Actor extends Vertex<Actor> implements Activatable
social network.
In usual diffusion models for the spread of an idea or innovation through a
social network,
each individual actor is either active (an adopter of the innovation) or inactive.
An inactive actor is activated if the influence of its incident neighbors,
each given by corresponding weighted edges, in sum outvalue its threshold.
