Add an overloaded function clusterCoefficient () that takes an integer argument k to SmallWorld (PROGRAM 4.5.5) so that it computes a local cluster coefficient for the graph based on the total edges present and the total edges possible among the set of vertices within distance k of each vertex. When k is equal to 1, the function produces results identical to the no-argument version of the function.
