Added bootstrap-sass gem.
Added autoprefixer-rails gem. Recommended for working with Bootstrap. It adds browser vendor prefixes automatically. More information at https://github.com/ai/autoprefixer-rails
changed autogenerated application.css to application.css.scss to leverage scss/sass
added require bootstrap to application.js
Added a page_title helper to the application helper. This sets a default base_title and combines it with a page title local variable (to be set in the controller actions). The default base_title (currently 'Simple Data') will always display and will be combined with the page_title if it is set. So, for example, on the landing page we could set the @page_title to be 'Home' and the resulting title would display as 'Home | Simple Data'. The order is set to accomodate usability and screen readers most effectively.
fixed formatting on the application helper
added page_title method to the application layout to allow for titles to be autogenerated
created empty header partial to hold main header/navigation view data
updated application.html.haml to put all the content into a .container class. This will help us leverage bootstrap moving forward
