RSS Reader (no persistence)

## Refactoring

The refactoring task is completed in all branches. See the readme in that folder for a description of what I did. 

## RSS Reader 

I created an RSS reader that uses jQuery and Rails UJS to create a single page application. Simply enter a valid RSS/Atom URL and the page will be updated to display your articles. The articles have tool tips set up on hover so you can see a preview. When you click on a link, the article will be shown in a modal unless the feed prohibits that. In that case, you will be shown a link to the article. 

The article and feed URLs are base64 encoded when making a call to #posts in the HomeController. This allows us to avoid any database persistence and allows us to use as much JS as possible.
