Iceberg Update: Sorting, Coloring, Resizing...

1. Converted Parallel Coordinates (parallel.js) to CoffeeScript.
2. Everything is handled by vis.coffee and index.html.
3. One data file, data is read from a1-cereals.csv rather than
cereals.json.
4. Improved sorting, coloring, and resizing options in the menu.
5. Flat design = implemented
6. When a node is selected, it is highlighted on every chart visible.
Cleaned up the code. Everything works great!
