title: How to get a MongoDatabase when using appharbor and mongohq
body: <p>I am starting a new project and wanting to use appharbor and mongohq.  The example for this on appharbor seems invalid since it uses MongoDatabase.Create and that is now obsolete.  I was hoping that there was an updated guide or example that users MongoClient, MongoServer, and MongoDatabase as is recommended.</p>
  
  <p>Is there another way to build get an instance of MongoDatabase with the key provided?</p>
