 * Loads, starts and initializes the Tuna server. We separate the server from this the loader so we
 * can have multiple loaders - the mocha tester has its own loader so we can mount the server from tests.
 * 
 * Start your debugger on this file to launch a web server.
 * Perf : raw startup time (node index) is 3200 ms
