title: Meteor lepozepo:s3 - Reference Error S3 is not defined
body: <p>I'm trying to use <code>lepozepo:s3</code> for a new project. </p>
  
  <p>On the client this seems to work fine: </p>
  
  <pre><code>console.log(S3);
  S3.config = {
    key: Meteor.settings.private.awsS3.access_key,
    secret: Meteor.settings.private.awsS3.secret,
    bucket: Meteor.settings.private.awsS3.bucket,
    region: Meteor.settings.private.awsS3.region,
  }
  console.log(S3);
  </code></pre>
  
  <p>This shows clearly hat the S3 object is defined before the call to the configuration and then later updated. </p>
  
  <p>On the client, however, I am getting a reference error when trying to implement the upload function or helper as per the documentation. </p>
  
  <pre><code>Template.upload.helpers({
    "files": function () {
      console.log(S3);
      return S3.collection.find();
    }
  })
  </code></pre>
  
  <p>I'm not doing any imports but have tried before to <code>import S3 from "meteor/lepozepo:s3"</code> and S3 ended up being <code>{}</code> and empty object. </p>
