DESM-viz CLI

[jbeard4]

Package desm-viz in command-line with the following interface:

schviz foo.scxml

Command-line will watch file foo.scxml and push changes to a browser instance running desm-viz, which will re-render the layout.

There are two possible approaches to this:

• Either start a web server and open a browser window with a websocket connection to the web server, OR
• Use node-webkit or atom-shell

This can be combined with #51 to animate the visualization in realtime as the use edits the document
