* Defined the new draft path which will be used to handle the new draft template
* Added the new HTML content to the application.hbs and have separated the header and footer to partial templates.
* Added the styles related to the new html content and made changes to the index.html to accommodate the new styles corresponding to the new draft html.
* Re-organized the app folder structure to accommodate routes, models, and controller definitions into separate files.
