// TODO: Replace examples and use TDD development by writing your own tests
// These are some CW specific test methods available:
// Test.expect(boolean, [optional] message)
// Test.assertEquals(actual, expected, [optional] message)
// Test.assertSimilar(actual, expected, [optional] message)
// Test.assertNotEquals(actual, expected, [optional] message)
// NodeJS assert is also automatically required for you.
// assert(true)
// assert.strictEqual({a: 1}, {a: 1})
// assert.deepEqual({a: [{b: 1}]}, {a: [{b: 1}]})
// You can also use Chai (http://chaijs.com/) by requiring it yourself
// var expect = require("chai").expect;
// var assert = require("chai").assert;
// require("chai").should();
