Add /lib in folder structure
New folder called lib with router.js in it that configures iron:router to play nice with the templates. Also added a route for the postsList, and make the root path '/'
Most this code is moved from the main.html into this to clean up the orginization of the app. The {{> yeild}} is for dynamic content, such as postList and postSubmition
Moved this code to views/application/layout
