Lab 4 - extra dependency requiring

[bahrieinn]

ex: in employee.actions.spec.js, underscore, React, TestUtils, and fluxDispatcher are required, so this doesn't need to be in a beforeEach block:

  var React, TestUtils, _, fluxDispatcher;

  beforeEach(function () {
    React = require('react/addons');
    TestUtils = React.addons.TestUtils;
    _ = require('lodash');
    fluxDispatcher = require('../flux/flux.dispatcher');
  });
