Lazy Home: Lazy load latest blog posts and assets and group by week and

project.

Javascript tutti.js and timeline.js is needed, and then the following to
init the timeline:

$('.timeline')
    .timeline({
        url: '/api/timeline'
    });

# Javascript Notes:
## ES6 transpile:
* Files in src/scripts/js/es6/common will be transpiled from
modern es6 js to old es5 js, and then added to tutti.js
* Files in src/scripts/js/es6/individual will be transpiled from
modern es6 js to old es5 js to individual module files
## JS Testing
* Added the Jest test framework to write javascript tests.
* `npm test` will run all the javascript tests
