hello world passes with scalatest

I did some research into scalatest and specs2. You should check out this [SO QA](http://stackoverflow.com/questions/2220815/whats-the-difference-between-scalatest-and-scala-specs-unit-test-frameworks) for my reasoning. I just liked scalatest way more in what it can offer and its syntax.

I had a bit of difficulty in the tests. [The main one was from this problem.](http://stackoverflow.com/questions/24076259/hello-world-scalatest-failing-not-found-type-myscalatraservlet) Basically, at the beginning of every spec, make sure you include `package com.graphular.app`.
