This method transmits the CytoscapeWindowClass's graph data, from R to
Cytoscape: nodes, edges, node and edge attributes, and displays it in a
window titled as specified by the objects 'title' slot. With large
graphs, this transmission may take a while. (todo: provide a few
timing examples.) The resulting view, in Cytoscape, of the network will
need layout and vizmap rendering; layout so that all the nodes and edges
can be seen; rendering so that data attributes can control the
appearance of the the nodes and edges.
