Added chai and mocha to package.json
* Changed tabs to 4 spaces
Added first failing mocha test for level model
* implemented checkStatus method in Level
pass checkStatus test && add mocha deps
    * in order to test client side code, we need a runner.html file
        * this file loads up all of mochas deps, similar to how
        jasmine had a specRunner file
    * beforeEach currently giving us a timed out error. wtf?
