Lightweight node server which get CTA Tracker data and converts it
Any incoming request does the same thing, which is get the routes info from the CTA Bus Tracker API (xml), and converts it to json.
Because (apparently) the tracker api does not suport CORS having a server ask for the data as a direct request allows the result to be incorporated into something like Angular in a $resource.get() call.
Converting the xml to json makes it easier for Angular to consume.
