in <code>data.edges</code> passed on <code>network</code> creation<br/>
                    With each layer of clustering, copies of the edges between clusters are created and the previous edges are hidden, until the cluster is opened.<br/>
                    This method takes an edgeId (ie. a base edgeId from <data>data.edges</code>) and applys the options to it and any edges that were created from it while clustering.<br><br> Example:
                    <code>network.clustering.updateEdge(originalEdge.i
