Resolve JS hint errors

Minor touch up so it passes validation
PhantomJS currently works fine as tested this simple script:

    "use strict";
    var CSV = require('./csv.js');
    console.log("out: ", CSV.parse("1,2,3"));
    phantom.exit();

With output: 
    $ phantomjs phantom.js
    out:  1,2,3

I also tested loading the unit test page through a phantomjs webpage.open and saw no error.  Chrome definitely works fine with a head, so something else must be going on.  I'll look into a Karma.  I'd like to confirm that I can reproduce the problem before starting any cleanup.
