Goal: Replace GoogleSpreadSheetPrinter.js and its calling code with an Ember Component

Inspired by https://speakerdeck.com/tehviking/bring-fun-back-to-js-refactoring-toward-ember

Breaking down of the steps via http://frontside.io/blog/2014/03/06/a-sprinkling-of-ember.html and work done in http://emberjs.jsbin.com/zunedenono/3/edit and http://emberjs.jsbin.com/zikupe/10/edit?html,js,output

Steps

1. Introduce Ember / Handlebars
2. Create a placeholder div for the component
3. Link to source files for Ember, Handlebars, jQuery
4. Create an Ember component
5. Make sure you specify the layoutName to match the data-template-name of your handlebars template
6. Use jQuery to replace your html div with your Ember component.
7. Be able to run it locally.
8. Remove dead code
