Add unit tests and clean up code

[mtruj013]

Done

• Added unit tests
• Cleaned up code a bit
  • After we launched the rebranded version of c.com we got feedback asking us to run our code through an HTML validator so I've done that here and implemented minor markup changes
  • Fixed indentation where needed

NOT TO BE MERGED UNTIL TUESDAY OR IT WILL KILL THE DEMO THAT IS CURRENTLY IN REVIEW WITH STAKEHOLDERS

QA

• See that tests pass
