title: How to include my nodejs libraries with Google Cloud Functions
body: <p>I've just made my first decent Google Cloud Function and now I'd like to refactor it into libraries.</p>
  
  <p>Example, I've got my Cloud Function and I'd like to require a library I've created, not something installed from NPM.</p>
  
  <p>How do I deploy these libraries to Google Cloud Functions?</p>
