mongo-scala-driver: Getting Results
<p>I have the following document in Mongodb:</p>

<pre><code>{ "index_column" : "site_id", "mapped_column":"site_name"}
</code></pre>

<p>I'm using the mongo-scala-driver from my scala code to query the server. How do I get the mapped_column to a scala String variable? I tried with the following code:</p>

<pre><code>val result = mongocollection.find(equal("index_column", data)).first()
</code></pre>

<p>It returns a <code>org.mongodb.scala.ObservableImplicits$BoxedObservable@207c9b87
</code>
Is it possible to convert the Observable to an Iterator? I just need the mapped_column value in a scala String variable.</p>
