RadialityCentrality
RadialityCentrality[g] gives a list of radiality centralities for the vertices in the graph g.
RadialityCentrality[g,"In"] gives a list of in-centralities for a directed graph g.
RadialityCentrality[g,"Out"] gives a list of out-centralities for a directed graph g.
RadialityCentrality[{v->w,…},…] uses rules v->w to specify the graph g.
