title: List files on S3
body: <p>I'm getting frustrated by not finding any good explanation on how to list all files in a S3 bucket.</p>
  
  <p>I have this bucket with about 20 images on. All I want to do is to list them. Someone says "just use the S3.list-method". But without any special library there is no S3.list-method. 
  I have a S3.get-method, which I dont get to work. Arggh, would appreciate if someone told me how to simply get an list of all files(filenames) from an S3 bucket. </p>
  
  <pre><code>val S3files = S3.get(bucketName: String, path: Option[String], prefix: Option[String], delimiter: Option[String])
  </code></pre>
  
  <p>returns an Future[Response]</p>
  
  <p>I dont know how to use this S3.get.
  What would be the easiest way to list all files in my S3 bucket?</p>
  
  <p>Answers much appreciated!</p>
