title: Scala example to help solidify book knowledge
body: <p>I've almost completed the scala book, and I want some nice code sample that would help me solidify what I have learned.</p>
  
  <p>Is there anything on github that you can recommend?</p>
  
  <p>Preferably some sort of library that I could learn from, maybe an API wrapper?  or maybe something else that you recommend?</p>
