#328 Have Cytoscape.JS working up to loading labels. Performance isn't quite up to snuff, but it looks cleaner in code. When I have it completed, or closer to completed, I can evaluate to see if it is still cleaner than in D3.
#328 Have Cytoscape.JS working up to arc scaling. The major feature missing is popup labels. It is half as fast as the D3 version, but has a significantly smaller code footprint. I think I am moving on to try Javascript Infovis Toolkit (JIT). Can clean up the cyto code later if desired.
