Write a Class to Get the Title of the Latest Blog Entry

======

I've created a simple project structure with some code to get you started.

0. Click the `Fork` button in the upper part of the screen

    - right below  `Account Settings` and `Help` links

0. One it is done forking clone the repo to your Projects directory

    - `cd ~/projects` and then `git clone git@github.com:YOUR_GITHUB_LOGIN/blog_title.git`

Expected Result

======

When you run `./blog_title.rb` it should display the title of the latest blog entry, for example:

    $ ./blog_title.rb

    Course Curriculum

Requirements

======

0. It will need to accept a URL when you create a new object.

0. Blog objects will need a "latest_title" method that returns the title of the latest blog entry.

Tools

======

We're going to need to familiarize ourselves with a couple of tools in order to acomplish this task.

net/http

------

net/http lets us obtain the body of a web page.

- API: http://rubydoc.info/stdlib/net/1.9.2/Net/HTTP

hpricot

------

hpricot parses HTML for us, so we don't have to.

- API: http://rubydoc.info/gems/hpricot/0.8.4/frames

- Take a look at these especially:

    0. http://rubydoc.info/gems/hpricot/0.8.4/file/README.md#Load_an_HTML_Page

    0. http://rubydoc.info/gems/hpricot/0.8.4/file/README.md#Search_for_Elements

Hints

======

0. Your class goes in `./lib/blog.rb`, don't change the `blog_title.rb`.

0. You'll need to install the hpricot gem: `gem install hpricot`

0. The XPath for the HTML element you want to look for is at: `/html/body/div[2]/div/div[2]/div/div/h3`

0. You'll see the error `./blog_title.rb:15:in '': uninitialized constant Object::Blog (NameError)` and then you'll know you can start coding.
