title: package.json dependencies for firebase
body: <p>Hey I am new to bluemix. 
  I wanted to create a webapp that stores info in firebase. However I realized I couldnt run 'npm install' on bluemix. I was told to update the package.json files of my app. </p>
  
  <p>For firebase what do I have to write in the package.json to get it working?</p>
