Updating the home controller

If you take a look at our current home controller (controllers/home.js), you can see that the index function barely has any code in it whatsoever:

res.render('index');

The first thing we want to do is build a basic view model using sample data so that we can see our view model at work. Replace that single res.render call with the following updated code:

var viewModel = {
    images: [
        {
            uniqueId:       1,
            title:          'Sample Image 1',
            description:    '',
            filename:       'sample1.jpg',
            views:          0,
            likes:          0,
            timestamp:      Date.now
        }, {
            uniqueId:       2,
            title:          'Sample Image 2',
            description:    '',
            filename:       'sample2.jpg',
            views:          0,
            likes:          0,
            timestamp:      Date.now
        }, {
            uniqueId:       3,
            title:...
