Implement Node.js and AngularJS

The iframe is out of sync with code changes in the main page. You currently have to copy the index.html and remove the description. To do any code re-use we need to start a back end to handle it.

I'm also doing well testing out Open Trips planning tool for actually getting an accessible transit route and want to get that code into a framework. Having attended LibertyJS this weekend, I'm interested in playing with AngularJS and Node.

So that needs to be implemented. The successful resolution of this issue will just mean cloning Node and Angular and having the files sitting in the same directory of the work already done.
