Get more familiar with using APIs and their JSON contents in Ruby.

Scraping sites is one way to get data but many times, companies will expose more data through their application programming interfaces, or APIs. For this todo, we're going to focus on Spotify's chart API.

• This is a test-driven lab so just get those specs to pass. Remember to start with the first specs then move to the later ones as they build on each other!
• If you get stuck, refer to the docs, the resources below, and take a look at these urls and try to pattern match:
  • http://charts.spotify.com/api/charts/
  • http://charts.spotify.com/api/charts/most_shared

• Make a command line app that interacts with the API.

• StackOverflow - JSON.load
• RubyDocs - JSON Load Method
